使用该函数需要先Use Excel2010
//DataSet导出Excel2010格式
//FileName=待导出的Excel的文件名,不带路径以及后缀;TitleLine1=导出后Excel第一表头,TitleLine2=Excel第二表头;CellsNames=Excel表格中Field的Title名称;
//IsOpen=是否马上打开 procedure sysDSetToXlsx(DSet: TADODataSet;FileName,TitleLine1,TitleLine2:String; CellsNames: TStringList; IsOpen: Boolean = False); var ExcelApp: TExcelApplication; ExcelWorkBook: TExcelWorkbook; ExcelWorkSheet: TExcelWorksheet; Range: OleVariant; I,RecNo: Integer; TmpPath: string; begin try ExcelApp := TExcelApplication.Create(nil); ExcelWorkBook := TExcelWorkbook.Create(nil); ExcelWorkSheet := TExcelWorksheet.Create(nil); except msgRaise(‘没有安装office 2007或以上版本,请安装后再试‘); end; //创建Excel ExcelApp.Connect; ExcelApp.Workbooks.Add(null,0); ExcelWorkBook.ConnectTo(ExcelApp.Workbooks[1]); ExcelWorkSheet.ConnectTo(ExcelWorkBook.Worksheets[1] as _WorkSheet); //构造Excel表头 Range := ExcelApp.Range[ExcelWorkSheet.Cells.Item[1,1],ExcelWorkSheet.Cells.Item[2,CellsNames.Count]]; Range.MergeCells := True; Range.Font.Size := 18; Range.Font.Bold := True; Range.HorizontalAlignment := 3; //横向居中,此处如果使用xlCenter报“类Range” 错误 Range.VerticalAlignment := 2; //竖向居中,此处如果使用xlCenter报“类Range” 错误 Range.RowHeight := 40; Range.Cells[1,1] := TitleLine1; //表头第一行 Range := ExcelApp.Range[ExcelWorkSheet.Cells.Item[3,1],ExcelWorkSheet.Cells.Item[3,CellsNames.Count]]; Range.MergeCells := True; //合并 Range.Font.Size := 10; Range.Font.Bold := True; Range.HorizontalAlignment := 4; //同上错误 Range.VerticalAlignment := 2; //同上错误 Range.RowHeight := 20; Range.Cells[1,1] := TitleLine2; //表头第二行 for I := 1 to CellsNames.Count do begin Range.Cells[2,I] := CellsNames.Names[I-1]; //需与DSet的Fields顺序保持一致 Range.Columns[I].ColumnWidth := CellsNames.Values[CellsNames.Names[I-1]]; //Excel文件中的单元格宽,单位为字符. end; RecNo := DSet.RecNo; DSet.DisableControls; DSet.First; while not DSet.Eof do begin for I := 1 to CellsNames.Count do Range.Cells[DSet.RecNo + 2, I] := VarToStr(DSet.Fields[I-1].Value); DSet.Next; end; DSet.RecNo := RecNo; DSet.EnableControls; TmpPath := sysGetPath(HInstance) + ‘xls\‘; //sysGetPath=自定义函数,获取当前路径 if not DirectoryExists(TmpPath) then ForceDirectories(TmpPath); ExcelWorkSheet.SaveAs(TmpPath + FileName + ‘.xlsx‘); ExcelWorkSheet.Disconnect; ExcelWorkBook.Disconnect; ExcelApp.Quit; //这句比较重要,很多例子中没有这句,关闭后,进程中还是能够发现Excel进程没有关闭 ExcelApp.Disconnect; FreeAndNil(ExcelWorkSheet); FreeAndNil(ExcelWorkBook); FreeAndNil(ExcelApp); if IsOpen then sysExecuteFile(TmpPath + FileName + ‘.xlsx‘,‘‘,‘‘,0); end;
