使用Delphi 控件方法
在Form中分别放入ExcelApplication, ExcelWorkbook和ExcelWorksheet。
1) 打开Excel
ExcelApplication1.Connect;
2) 显示当前窗口:
ExcelApplication1.Visible[0]:=True;
3) 更改 Excel 标题栏:
ExcelApplication1.Caption := '应用程序调用 Microsoft Excel';
4) 添加新工作簿:
ExcelWorkbook1.ConnectTo(ExcelApplication1.Workbooks.Add(EmptyParam,0));
5) 添加新工作表:
var Temp_Worksheet: _WorkSheet;
begin
Temp_Worksheet:=ExcelWorkbook1.
WorkSheets.Add(EmptyParam,EmptyParam,EmptyParam,EmptyParam,0) as _WorkSheet;
ExcelWorkSheet1.ConnectTo(Temp_WorkSheet);
End;
6) 打开已存在的工作簿:
ExcelApplication1.Workbooks.Open (c:/a.xls
EmptyParam,EmptyParam,EmptyParam,EmptyParam,
EmptyParam,EmptyParam,EmptyParam,EmptyParam,
EmptyParam,EmptyParam,EmptyParam,EmptyParam,0)
7) 设置第2个工作表为活动工作表:
ExcelApplication1.WorkSheets[2].Activate; 或
ExcelApplication1.WorksSheets[ 'Sheet2' ].Activate;
8) 给单元格赋值:
ExcelApplication1.Cells[1,4].Value := '第一行第四列';
9) 设置指定列的宽度(单位:字符个数),以第一列为例:
ExcelApplication1.ActiveSheet.Columns[1].ColumnsWidth := 5;
10) 设置指定行的高度(单位:磅)(1磅=0.035厘米),以第二行为例:
ExcelApplication1.ActiveSheet.Rows[2].RowHeight := 1/0.035; // 1厘米
11) 在第8行之前插入分页符:
ExcelApplication1.WorkSheets[1].Rows[8].PageBreak := 1;
12) 在第8列之前删除分页符:
ExcelApplication1.ActiveSheet.Columns[4].PageBreak := 0;
13) 指定边框线宽度:
ExcelApplication1.ActiveSheet.Range[ 'B3:D4' ].Borders[2].Weight := 3;
1-左 2-右 3-顶 4-底 5-斜( / ) 6-斜( / )
14) 清除第一行第四列单元格公式:
ExcelApplication1.ActiveSheet.Cells[1,4].ClearContents;
15) 设置第一行字体属性:
ExcelApplication1.ActiveSheet.Rows[1].Font.Name := '隶书';
ExcelApplication1.ActiveSheet.Rows[1].Font.Color := clBlue;
ExcelApplication1.ActiveSheet.Rows[1].Font.Bold := True;
ExcelApplication1.ActiveSheet.Rows[1].Font.UnderLine := True;
16) 进行页面设置:
a.页眉:
ExcelApplication1.ActiveSheet.PageSetup.CenterHeader := '报表演示';
b.页脚:
ExcelApplication1.ActiveSheet.PageSetup.CenterFooter := '第&P页';
c.页眉到顶端边距2cm:
ExcelApplication1.ActiveSheet.PageSetup.HeaderMargin := 2/0.035;
d.页脚到底端边距3cm:
ExcelApplication1.ActiveSheet.PageSetup.HeaderMargin := 3/0.035;
e.顶边距2cm:
ExcelApplication1.ActiveSheet.PageSetup.TopMargin := 2/0.035;
f.底边距2cm:
ExcelApplication1.ActiveSheet.PageSetup.BottomMargin := 2/0.035;
g.左边距2cm:
ExcelApplication1.ActiveSheet.PageSetup.LeftMargin := 2/0.035;
h.右边距2cm:
ExcelApplication1.ActiveSheet.PageSetup.RightMargin := 2/0.035;
i.页面水平居中:
ExcelApplication1.ActiveSheet.PageSetup.CenterHorizontally := 2/0.035;
j.页面垂直居中:
ExcelApplication1.ActiveSheet.PageSetup.CenterVertically := 2/0.035;
k.打印单元格网线:
ExcelApplication1.ActiveSheet.PageSetup.PrintGridLines := True;
17) 拷贝操作:
a.拷贝整个工作表:
ExcelApplication1.ActiveSheet.Used.Range.Copy;
b.拷贝指定区域:
ExcelApplication1.ActiveSheet.Range[ 'A1:E2' ].Copy;
c.从A1位置开始粘贴:
ExcelApplication1.ActiveSheet.Range.[ 'A1' ].PasteSpecial;
d.从文件尾部开始粘贴:
ExcelApplication1.ActiveSheet.Range.PasteSpecial;
18) 插入一行或一列:
a. ExcelApplication1.ActiveSheet.Rows[2].Insert;
b. ExcelApplication1.ActiveSheet.Columns[1].Insert;
19) 删除一行或一列:
a. ExcelApplication1.ActiveSheet.Rows[2].Delete;
b. ExcelApplication1.ActiveSheet.Columns[1].Delete;
20) 打印预览工作表:
ExcelApplication1.ActiveSheet.PrintPreview;
21) 打印输出工作表:
ExcelApplication1.ActiveSheet.PrintOut;
22) 工作表保存:
if not ExcelApplication1.ActiveWorkBook.Saved then
ExcelApplication1.ActiveSheet.PrintPreview;
23) 工作表另存为:
ExcelApplication1.SaveAs( 'C:/Excel/Demo1.xls' );
24) 放弃存盘:
ExcelApplication1.ActiveWorkBook.Saved := True;
25) 关闭工作簿:
ExcelApplication1.WorkBooks.Close;
26) 退出 Excel:
ExcelApplication1.Quit;
ExcelApplication1.Disconnect;Top
把数据集导如导excel,adsdata可以换成任意你用导的数据集
WriteExcel(AdsData:Tclientdataset; sName, Title: string);
var
ExcelApplication1: TExcelApplication;
ExcelWorksheet1: TExcelWorksheet;
ExcelWorkbook1: TExcelWorkbook;
i, j: integer;
filename: string;
begin
filename := concat(sName, '.xls');
try
ExcelApplication1 := TExcelApplication.Create(Application);
ExcelWorksheet1 := TExcelWorksheet.Create(Application);
ExcelWorkbook1 := TExcelWorkbook.Create(Application);
ExcelApplication1.Connect;
except
Application.Messagebox('Excel没有安装!','Hello',MB_ICONERROR + mb_Ok);
Abort;
end;
try
ExcelApplication1.Workbooks.Add(EmptyParam, 0);
ExcelWorkbook1.ConnectTo(ExcelApplication1.Workbooks[1]);
ExcelWorksheet1.ConnectTo(ExcelWorkbook1.Worksheets[1] as _worksheet);
AdsData.First;
for j := 0 to AdsData.Fields.Count - 1 do
begin
ExcelWorksheet1.Cells.item[3, j + 1] := AdsData.Fields[j].DisplayLabel;
ExcelWorksheet1.Cells.item[3, j + 1].font.size :='10';
end;
for i := 4 to AdsData.RecordCount + 3 do
begin
for j := 0 to AdsData.Fields.Count - 1 do
begin
ExcelWorksheet1.Cells.item[i, j + 1] :=
AdsData.Fields[j].Asstring;
ExcelWorksheet1.Cells.item[i, j + 1].font.size := '10';
end;
AdsData.Next;
end;
ExcelWorksheet1.Columns.AutoFit;
ExcelWorksheet1.Cells.item[1, 2] := Title;
ExcelWorksheet1.Cells.Item[1, 2].font.size :='14';
ExcelWorksheet1.SaveAs(filename);
Application.Messagebox(pchar('数据成功导出'+ filename),'信息化建设部',mb_Ok);
finally
ExcelApplication1.Disconnect;
ExcelApplication1.Quit;
ExcelApplication1.Free;
ExcelWorksheet1.Free;
ExcelWorkbook1.Free;
end;
end;
