java poi實(shí)現(xiàn)Excel多級(jí)表頭導(dǎo)出(多級(jí)表頭,復(fù)雜表頭)
最近碰到一個(gè)導(dǎo)出,比較繁瑣,也查詢了許多博客,在其中一篇博客的基礎(chǔ)上修改,實(shí)現(xiàn)了最終想要的效果。
話不多說,直接上效果圖:
上代碼
1.主代碼
List<Map<String, Object>> convertListMap = toListConvertListMap(tableTitleList, list); // 第一步,創(chuàng)建一個(gè)Workbook,對(duì)應(yīng)一個(gè)Excel文件 XSSFWorkbook wb = new XSSFWorkbook(); // 第二步,在Workbook中添加一個(gè)sheet,對(duì)應(yīng)Excel文件中的sheet XSSFSheet sheet = wb.createSheet("sheet"); // 第三步,設(shè)置樣式以及字體樣式 XSSFCellStyle titleStyle = createTitleCellStyle(wb); XSSFCellStyle headerStyle = createHeadCellStyle(wb); XSSFCellStyle contentStyle = createContentCellStyle(wb); // 行號(hào) int rowNum = 0; // 創(chuàng)建第一頁(yè)的第一行,索引從0開始 XSSFRow row0 = sheet.createRow(rowNum++); row0.setHeight((short) 600);// 設(shè)置行高 sheet.setColumnWidth(2, 8000); sheet.setColumnWidth(3, 8000); //第二行 XSSFRow row2 = sheet.createRow(rowNum++); row2.setHeight((short) 700); // todo: 第三行 XSSFRow row3 = sheet.createRow(rowNum++); row3.setHeight((short) 700); String[] row_one = null; String[] row_two = null; String[] row_three = null; int cellSize = 0; if (tableTitleList.size() == 2) { // 全部 row_one = new String[]{"序號(hào)", "所屬模塊", "單位名稱", "情況統(tǒng)計(jì)", "合計(jì)", "", "", "測(cè)試類型A", "", "", "", "", "", "", "", "", "", "", "", "測(cè)試類型B", "", "", "", "", "", "", "", "", "", "", "",}; row_two = new String[]{"", "", "", "", "合計(jì)A", "合計(jì)B", "合計(jì)C", "測(cè)試類型A1", "", "", "", "測(cè)試類型A2", "", "", "", "測(cè)試類型A3", "", "", "", "測(cè)試類型B1", "", "", "", "測(cè)試類型B2", "", "", "", "測(cè)試類型B3", "", "", ""}; row_three = new String[]{"", "", "", "", "", "", "", "起床", "洗漱", "吃飯", "上班", "起床", "洗漱", "吃飯", "上班", "起床", "洗漱", "吃飯", "上班", "起床", "洗漱", "吃飯", "上班", "起床", "洗漱", "吃飯", "上班", "起床", "洗漱", "吃飯", "上班",}; // 合并單元格 extracted(sheet); } // 創(chuàng)建第一行單元格 for (int i = 0; i < row_one.length; i++) { XSSFCell c00 = row0.createCell(i); c00.setCellValue(row_one[i]); c00.setCellStyle(headerStyle); } // 創(chuàng)建第二行單元格 for (int i = 0; i < row_two.length; i++) { XSSFCell tempCell = row2.createCell(i); tempCell.setCellValue(row_two[i]); tempCell.setCellStyle(headerStyle); } // 創(chuàng)建第三行單元格 for (int i = 0; i < row_three.length; i++) { XSSFCell tempCell = row3.createCell(i); tempCell.setCellValue(row_three[i]); tempCell.setCellStyle(headerStyle); } // 設(shè)置表頭單元格的寬度 tableTitleStyleColumnwidth(sheet); // todo: 填充數(shù)據(jù) approvalMethodfillInData(convertListMap, sheet, contentStyle, rowNum, row_three, tableTitleList); // approvalMethodfillInData(convertListMap, sheet, contentStyle, rowNum, cellSize, tableTitleList); //導(dǎo)出到瀏覽器下載 buildExcelDocument("監(jiān)測(cè)數(shù)據(jù).xlsx", wb, response);
2.合并單元格
private static void extracted(XSSFSheet sheet) { // todo: 合并參數(shù)分別為: 起始行,結(jié)束行,起始列,結(jié)束列 // 將第一列 的 第一行到第三行合并 sheet.addMergedRegion(new CellRangeAddress(0, 2, 0, 0)); // 將第二列的 第一行到第三行合并 sheet.addMergedRegion(new CellRangeAddress(0, 2, 1, 1)); // 將第三列的 第一行到第三行合并 sheet.addMergedRegion(new CellRangeAddress(0, 2, 2, 2)); sheet.addMergedRegion(new CellRangeAddress(0, 2, 3, 3)); // 合計(jì) sheet.addMergedRegion(new CellRangeAddress(0, 0, 4, 6)); // 合計(jì)下的單元格 sheet.addMergedRegion(new CellRangeAddress(1, 2, 4, 4)); sheet.addMergedRegion(new CellRangeAddress(1, 2, 5, 5)); sheet.addMergedRegion(new CellRangeAddress(1, 2, 6, 6)); sheet.addMergedRegion(new CellRangeAddress(0, 0, 7, 18)); sheet.addMergedRegion(new CellRangeAddress(0, 0, 19, 30)); sheet.addMergedRegion(new CellRangeAddress(1, 1, 7, 10)); sheet.addMergedRegion(new CellRangeAddress(1, 1, 11, 14)); sheet.addMergedRegion(new CellRangeAddress(1, 1, 15, 18)); sheet.addMergedRegion(new CellRangeAddress(1, 1, 19, 22)); sheet.addMergedRegion(new CellRangeAddress(1, 1, 23, 26)); sheet.addMergedRegion(new CellRangeAddress(1, 1, 27, 30)); }
3.設(shè)置表頭單元格的寬度
private static void tableTitleStyleColumnwidth(XSSFSheet sheet) { sheet.setColumnWidth(2, 8000); sheet.setColumnWidth(3, 8000); sheet.setColumnWidth(7, 3000); sheet.setColumnWidth(8, 3000); sheet.setColumnWidth(9, 3000); sheet.setColumnWidth(10, 3000); sheet.setColumnWidth(11, 3000); sheet.setColumnWidth(12, 3000); sheet.setColumnWidth(13, 3000); sheet.setColumnWidth(14, 3000); sheet.setColumnWidth(15, 3000); sheet.setColumnWidth(16, 3000); sheet.setColumnWidth(17, 3000); sheet.setColumnWidth(18, 3000); sheet.setColumnWidth(19, 3000); sheet.setColumnWidth(20, 3000); sheet.setColumnWidth(21, 3000); sheet.setColumnWidth(22, 3000); sheet.setColumnWidth(23, 3000); sheet.setColumnWidth(24, 3000); sheet.setColumnWidth(25, 3000); sheet.setColumnWidth(26, 3000); sheet.setColumnWidth(27, 3000); sheet.setColumnWidth(28, 3000); sheet.setColumnWidth(29, 3000); sheet.setColumnWidth(30, 3000); }
4.填充數(shù)據(jù)
(注:我這里的數(shù)據(jù)格式是List<Map<String, Object>>類型,可以根據(jù)自己的實(shí)際情況來(lái)封裝數(shù)據(jù))
private static void approvalMethodfillInData(List<Map<String, Object>> convertListMap, XSSFSheet sheet, XSSFCellStyle contentStyle, int rowNum, String[] cellSize, List<Object> tableTitleList) { for (Map<String, Object> map : convertListMap) { XSSFRow tempRow = sheet.createRow(rowNum++); tempRow.setHeight((short) 500); // 判斷選擇類型 if (tableTitleList.size() == 2 || "enterprise".equals(tableTitleList.get(0).toString())) { // 循環(huán)單元格填入數(shù)據(jù) for (int i = 0; i < cellSize.length; i++) { //列寬自適應(yīng),j為自適應(yīng)的列,true就是自適應(yīng),false就是不自適應(yīng),默認(rèn)不自適應(yīng) sheet.autoSizeColumn(i, true); XSSFCell tempCell = tempRow.createCell(i); tempCell.setCellStyle(contentStyle); String tempValue = ""; switch (i) { case 0: tempValue = map.get("indexNum").toString(); break; case 1: tempValue = map.get("platName").toString(); break; case 2: tempValue = map.get("deptName").toString(); break; case 3: tempValue = map.get("type").toString(); break; case 4: tempValue = map.get("totalProNum").toString(); break; case 5: tempValue = map.get("totalBidNum").toString(); break; case 6: tempValue = map.get("totalAmount").toString(); break; case 7: tempValue = map.get("enterpriseEngineeringProNum").toString(); break; case 8: tempValue = map.get("enterpriseEngineeringBidNum").toString(); break; case 9: tempValue = map.get("enterprisePurchaseAmount").toString(); break; case 10: tempValue = map.get("planEnterprisePurchaseAmount").toString(); break; case 11: tempValue = map.get("enterprisePurchaseProNum").toString(); break; case 12: tempValue = map.get("enterprisePurchaseBidNum").toString(); break; case 13: tempValue = map.get("enterprisePurchaseAmount").toString(); break; case 14: tempValue = map.get("planEnterprisePurchaseAmount").toString(); break; case 15: tempValue = map.get("enterpriseServiceProNum").toString(); break; case 16: tempValue = map.get("enterpriseServiceBidNum").toString(); break; case 17: tempValue = map.get("enterpriseServiceAmount").toString(); break; case 18: tempValue = map.get("planEnterpriseServiceAmount").toString(); break; case 19: tempValue = map.get("groupEngineeringProNum").toString(); break; case 20: tempValue = map.get("grouppurchaseBidNum").toString(); break; case 21: tempValue = map.get("groupPurchaseAmount").toString(); break; case 22: tempValue = map.get("palnGroupPurchaseAmount").toString(); break; case 23: tempValue = map.get("groupPurchaseProNum").toString(); break; case 24: tempValue = map.get("groupEngineeringBidNum").toString(); break; case 25: tempValue = map.get("groupEngineeringAmount").toString(); break; case 26: tempValue = map.get("planGroupEngineeringAmount").toString(); break; case 27: tempValue = map.get("groupServiceProNum").toString(); break; case 28: tempValue = map.get("groupServiceBidNum").toString(); break; case 29: tempValue = map.get("groupServiceAmount").toString(); break; case 30: tempValue = map.get("planGroupServiceAmount").toString(); break; } tempCell.setCellValue(tempValue); } } }
5.web下載,導(dǎo)出到瀏覽器
private static void buildExcelDocument(String fileName, Workbook wb, HttpServletResponse response) { try { response.setContentType("application/octet-stream"); // 可自行定義編碼格式 response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(fileName, "utf-8")); //清除jsp編譯html文件的空白,防止excel出現(xiàn)空行 response.flushBuffer(); //寫出 wb.write(response.getOutputStream()); } catch (IOException e) { e.printStackTrace(); } finally { IOUtils.closeQuietly(wb); } }
6.提供表頭樣式,內(nèi)容樣式以及標(biāo)題樣式
/** * 創(chuàng)建標(biāo)題樣式 * * @param wb * @return */ private static XSSFCellStyle createTitleCellStyle(XSSFWorkbook wb) { XSSFCellStyle cellStyle = wb.createCellStyle(); cellStyle.setAlignment(HorizontalAlignment.CENTER);//水平居中 cellStyle.setVerticalAlignment(VerticalAlignment.CENTER);//垂直對(duì)齊 cellStyle.setFillPattern(FillPatternType.SOLID_FOREGROUND); // cellStyle.setFillForegroundColor(IndexedColors.GREY_40_PERCENT.getIndex());//背景顏色 XSSFFont headerFont1 = (XSSFFont) wb.createFont(); // 創(chuàng)建字體樣式 headerFont1.setBold(true); //字體加粗 headerFont1.setFontName("黑體"); // 設(shè)置字體類型 headerFont1.setFontHeightInPoints((short) 15); // 設(shè)置字體大小 cellStyle.setFont(headerFont1); // 為標(biāo)題樣式設(shè)置字體樣式 return cellStyle; } /** * 創(chuàng)建表頭樣式 * * @param wb * @return */ private static XSSFCellStyle createHeadCellStyle(XSSFWorkbook wb) { XSSFCellStyle cellStyle = wb.createCellStyle(); cellStyle.setWrapText(true);// 設(shè)置自動(dòng)換行 cellStyle.setFillForegroundColor(IndexedColors.GREY_25_PERCENT.getIndex());//背景顏色 cellStyle.setAlignment(HorizontalAlignment.CENTER); //水平居中 cellStyle.setVerticalAlignment(VerticalAlignment.CENTER); //垂直對(duì)齊 cellStyle.setFillPattern(FillPatternType.SOLID_FOREGROUND); // cellStyle.setBottomBorderColor(IndexedColors.BLACK.index); cellStyle.setBorderBottom(BorderStyle.THIN); //下邊框 cellStyle.setBorderLeft(BorderStyle.THIN); //左邊框 cellStyle.setBorderRight(BorderStyle.THIN); //右邊框 cellStyle.setBorderTop(BorderStyle.THIN); //上邊框 XSSFFont headerFont = (XSSFFont) wb.createFont(); // 創(chuàng)建字體樣式 headerFont.setBold(true); //字體加粗 headerFont.setFontName("黑體"); // 設(shè)置字體類型 headerFont.setFontHeightInPoints((short) 12); // 設(shè)置字體大小 cellStyle.setFont(headerFont); // 為標(biāo)題樣式設(shè)置字體樣式 return cellStyle; } /** * 創(chuàng)建內(nèi)容樣式 * * @param wb * @return */ private static XSSFCellStyle createContentCellStyle(XSSFWorkbook wb) { XSSFCellStyle cellStyle = wb.createCellStyle(); cellStyle.setVerticalAlignment(VerticalAlignment.CENTER);// 垂直居中 cellStyle.setAlignment(HorizontalAlignment.CENTER);// 水平居中 cellStyle.setWrapText(true);// 設(shè)置自動(dòng)換行 cellStyle.setBorderBottom(BorderStyle.THIN); //下邊框 cellStyle.setBorderLeft(BorderStyle.THIN); //左邊框 cellStyle.setBorderRight(BorderStyle.THIN); //右邊框 cellStyle.setBorderTop(BorderStyle.THIN); //上邊框 // 生成12號(hào)字體 XSSFFont font = wb.createFont(); font.setColor((short) 8); font.setFontHeightInPoints((short) 12); cellStyle.setFont(font); return cellStyle; }
到此,大功告成!
總結(jié)
