            XlsDocument xls = new XlsDocument();
            Worksheet sheet = xls.Workbook.Worksheets.AddNamed(filename);//状态栏标题名称            int rowNum = dtData.Rows.Count;            int columnNum = dtData.Columns.Count;            int rowIndex = 1;            int columnIndex = 0;            //生成格式列
            ColumnInfo colInfo = new ColumnInfo(xls, sheet);
            colInfo.ColumnIndexStart = 0;
            colInfo.ColumnIndexEnd = Convert.ToUInt16(columnNum);
            colInfo.Width = 20 * 256;            sheet.AddColumnInfo(colInfo);            //绑定标题
            Cell cell = null;
            foreach (DataColumn dc in dtData.Columns)
            {
                columnIndex++;                cell = sheet.Cells.AddValueCell(rowIndex, columnIndex, dc.ColumnName);
