這篇文章主要介紹了Jsp中的table多表頭導出excel文件具體實現,有需要的朋友可以參考一下
首先引入兩份JS:copyhtmltoexcel.js以及 tableToExcel.js 代碼如下: /* * 默認轉換實現函數,如果需要其他功能,需自行擴展 * 參數: * tableID : HTML中Table對象id屬性值 * 詳細用法參見以下 TableToExcel 對象定義 */ function saveAsExcel(tableID){ var tb = new TableToExcel(tableID); tb.setFontStyle("Courier New"); tb.setFontSize(10); tb.setTableBorder(2); tb.setColumnWidth(7); tb.isLineWrap(false); tb.isAutoFit(true); tb.getExcelFile(); } /* * 功能:HTML中Table對象轉換為Excel通用對象. * 作者:Jeva * 時間:2006-08-09 * 參數:tableID HTML中Table對象的ID屬性值 * 說明: * 能適應復雜的HTML中Table對象的自動轉換,能夠自動根據行列擴展信息 * 合並Excel中的單元格,客戶端需要安裝有Excel * 詳細的屬性、方法引用說明參見:Excel的Microsoft Excel Visual Basic參考 * 示范: * var tb = new TableToExcel('demoTable'); * tb.setFontStyle("Courier New"); * tb.setFontSize(10); //推薦取值10 * tb.setFontColor(6); //一般情況不用設置 * tb.setBackGround(4); //一般情況不用設置 * tb.setTableBorder(2); //推薦取值2 * tb.setColumnWidth(10); //推薦取值10 * tb.isLineWrap(false); * tb.isAutoFit(true); * * tb.getExcelFile(); * 如果設置了單元格自適應,則設置單元格寬度無效 * 版本:1.0 */ function TableToExcel(tableID) { this.tableBorder = -1; //邊框類型,-1沒有邊框 可取1/2/3/4 this.backGround = 0; //背景顏色:白色 可取調色板中的顏色編號 1/2/3/4.... this.fontColor = 1; //字體顏色:黑色 this.fontSize = 10; //字體大小 this.fontStyle = "宋體"; //字體類型 this.rowHeight = -1; //行高 this.columnWidth = -1; //列寬 this.lineWrap = true; //是否自動換行 this.textAlign = -4108; //內容對齊方式 默認為居中 this.autoFit = false; //是否自適應寬度 this.tableID = tableID; } TableToExcel.prototype.setTableBorder = function (excelBorder) { this.tableBorder = excelBorder ; }; TableToExcel.prototype.setBackGround = function (excelColor) { this.backGround = excelColor; }; TableToExcel.prototype.setFontColor = function (excelColor) { this.fontColor = excelColor; }; TableToExcel.prototype.setFontSize = function (excelFontSize) { this.fontSize = excelFontSize; }; TableToExcel.prototype.setFontStyle = function (excelFont) { this.fontStyle = excelFont; }; TableToExcel.prototype.setRowHeight = function (excelRowHeight) { this.rowHeight = excelRowHeight; }; TableToExcel.prototype.setColumnWidth = function (excelColumnWidth) { this.columnWidth = excelColumnWidth; }; TableToExcel.prototype.isLineWrap = function (lineWrap) { if (lineWrap == false || lineWrap == true) { this.lineWrap = lineWrap; } }; TableToExcel.prototype.setTextAlign = function (textAlign) { this.textAlign = textAlign; }; TableToExcel.prototype.isAutoFit = function(autoFit){ if(autoFit == true || autoFit == false) this.autoFit = autoFit ; } //文件轉換主函數 TableToExcel.prototype.getExcelFile = function () { var jXls, myWorkbook, myWorksheet, myHTMLTableCell, myExcelCell, myExcelCell2; var myCellColSpan, myCellRowSpan; try { jXls = new ActiveXObject('Excel.Application'); } catch (e) { alert("無法啟動Excel!nn" + e.message + "nn如果您確信您的電腦中已經安裝了Excel,"+ "那麼請調整IE的安全級別。nn具體操作:nn"+ "工具 → Internet選項 → 安全 → 自定義級別 → ActiveX控件和插件 nn" + "→ 啟用 : 對沒有標記為安全的ActiveX控件進行初始化和腳本運行"); return false; } jXls.Visible = true; myWorkbook = jXls.Workbooks.Add(); jXls.DisplayAlerts = false; myWorkbook.Worksheets(3).Delete(); myWorkbook.Worksheets(2).Delete(); jXls.DisplayAlerts = true; myWorksheet = myWorkbook.ActiveSheet; var readRow = 0, readCol = 0; var totalRow = 0, totalCol = 0; var tabNum = 0; //設置行高、列寬 if(this.columnWidth != -1) myWorksheet.Columns.ColumnWidth = this.columnWidth; else myWorksheet.Columns.ColumnWidth = 7; if(this.rowHeight != -1) myWorksheet.Rows.RowHeight = this.rowHeight ; //搜索需要轉換的Table對象,獲取對應行、列數 var obj = document.all.tags("table"); for (x = 0; x < obj.length; x++) { if (obj[x].id == this.tableID) { tabNum = x; totalRow = obj[x].rows.length; for (i = 0; i < obj[x].rows[0].cells.length; i++) { myHTMLTableCell = obj[x].rows(0).cells(i); myCellColSpan = myHTMLTableCell.colSpan; totalCol = totalCol + myCellColSpan; } } } //開始構件模擬表格 var excelTable = new Array(); for (i = 0; i <= totalRow; i++) { excelTable[i] = new Array(); for (t = 0; t <= totalCol; t++) { excelTable[i][t] = false; } } //開始轉換表格 for (z = 0; z < obj[tabNum].rows.length; z++) { readRow = z + 1; readCol = 1; for (c = 0; c < obj[tabNum].rows(z).cells.length; c++) { myHTMLTableCell = obj[tabNum].rows(z).cells(c); myCellColSpan = myHTMLTableCell.colSpan; myCellRowSpan = myHTMLTableCell.rowSpan; for (y = 1; y <= totalCol; y++) { if (excelTable[readRow][y] == false) { readCol = y; break; } } if (myCellColSpan * myCellRowSpan > 1) {
