Delphi 控制Excel
(一) 使用动态创建的方法
首先创建 Excel
对象,使用ComObj:
var ExcelApp: Variant;
ExcelApp := CreateOleObject(
'Excel.Application' );
1) 显示当前窗口:
ExcelApp.Visible := True;
2) 更改 Excel
标题栏:
ExcelApp.Caption := '应用程序调用 Microsoft Excel';
3)
添加新工作簿:
ExcelApp.WorkBooks.Add;
4) 打开已存在的工作簿:
ExcelApp.WorkBooks.Open(
'C:\Excel\Demo.xls' );
5)
设置第2个工作表为活动工作表:
ExcelApp.WorkSheets[2].Activate; 或 ExcelApp.WorksSheets[
'Sheet2' ].Activate;
6) 给单元格赋值:
ExcelApp.Cells[1,4].Value :=
'第一行第四列';
7)
设置指定列的宽度(单位:字符个数),以第一列为例:
ExcelApp.ActiveSheet.Columns[1].ColumnsWidth :=
5;
8)
设置指定行的高度(单位:磅)(1磅=0.035厘米),以第二行为例:
ExcelApp.ActiveSheet.Rows[2].RowHeight :=
1/0.035; // 1厘米
9) 在第8行之前插入分页符:
ExcelApp.WorkSheets[1].Rows.PageBreak :=
1;
10) 在第8列之前删除分页符:ExcelApp.ActiveSheet.Columns[4].PageBreak := 0;
11)
指定边框线宽度:
ExcelApp.ActiveSheet.Range[ 'B3:D4' ].Borders[2].Weight :=
3;
1-左 2-右 3-顶 4-底 5-斜( \ ) 6-斜( / )
12)
清除第一行第四列单元格公式:
ExcelApp.ActiveSheet.Cells[1,4].ClearContents;
13)
设置第一行字体属性:ExcelApp.ActiveSheet.Rows[1].Font.Name :=
'隶书';
ExcelApp.ActiveSheet.Rows[1].Font.Color :=
clBlue;
ExcelApp.ActiveSheet.Rows[1].Font.Bold :=
True;
ExcelApp.ActiveSheet.Rows[1].Font.UnderLine := True;
14)
进行页面设置:
a.页眉:
ExcelApp.ActiveSheet.PageSetup.CenterHeader :=
'报表演示';
b.页脚:
ExcelApp.ActiveSheet.PageSetup.CenterFooter :=
'第&P页';
c.页眉到顶端边距2cm:
ExcelApp.ActiveSheet.PageSetup.HeaderMargin
:= 2/0.035;
d.页脚到底端边距3cm:
ExcelApp.ActiveSheet.PageSetup.HeaderMargin
:= 3/0.035;
e.顶边距2cm:

i.页面水平居中:
ExcelApp.ActiveSheet.PageSetup.CenterHorizontally :=
2/0.035;
j.页面垂直居中:
ExcelApp.ActiveSheet.PageSetup.CenterVertically :=
2/0.035;
k.打印单元格网线:
ExcelApp.ActiveSheet.PageSetup.PrintGridLines :=
True;
15) 拷贝操作:
a.拷贝整个工作表:
ExcelApp.ActiveSheet.Used.Range.Copy;
b.拷贝指定区域: ExcelApp.ActiveSheet.Range[
'A1:E2' ].Copy;
c.从A1位置开始粘贴: ExcelApp.ActiveSheet.Range.[ 'A1'
].PasteSpecial;
d.从文件尾部开始粘贴:
ExcelApp.ActiveSheet.Range.PasteSpecial;
16) 插入一行或一列:
a.
ExcelApp.ActiveSheet.Rows[2].Insert;
b.
ExcelApp.ActiveSheet.Columns[1].Insert;
17) 删除一行或一列:
a.
ExcelApp.ActiveSheet.Rows[2].Delete;
b.
ExcelApp.ActiveSheet.Columns[1].Delete;
18)
打印预览工作表:
ExcelApp.ActiveSheet.PrintPreview;
19)
打印输出工作表:
ExcelApp.ActiveSheet.PrintOut;
20) 工作表保存:
if not
ExcelApp.ActiveWorkBook.Saved then
ExcelApp.ActiveSheet.PrintPreview;
21) 工作表另存为:
ExcelApp.SaveAs(
'C:\Excel\Demo1.xls' );
22) 放弃存盘:
ExcelApp.ActiveWorkBook.Saved :=
True;
23) 关闭工作簿:
ExcelApp.WorkBooks.Close;
24) 退出
Excel:
ExcelApp.Quit;
(二) 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)

首先要创建一个公共单元,名字你们可以随便起。
以下是我创建的公共单元的全部代码:
unit UnitDatatoExcel;
interface
uses
Windows,Messages, SysUtils, Classes, Graphics, Controls, Forms,Dialogs,
DB, ComObj;
type
TKHTMLFormatCellEvent = procedure(Sender: TObject; CellRow,CellColumn: Integer; FieldName: string;
var CustomAttrs, CellData: string) of object;
TDataSetToExcel = class(TComponent)
private
FDataSet: TDataSet;
FOnFormatCell: TKHTMLFormatCellEvent;
public
constructor Create(AOwner: TComponent); override;
destructor Destroy; override;
procedure Transfer(const FileName: string; Title: string = ');
published
property DataSet: TDataSet read FDataSet write FDataSet;
end;
implementation
constructor TDataSetToExcel.Create(AOwner: TComponent);
begin
inherited Create(AOwner);
FDataSet := nil;
end;
destructor TDataSetToExcel.Destroy;
begin
inherited;
end;
procedure TDataSetToExcel.Transfer(const FileName:string;Title:string = ');
var
ExcelApp, MyWorkBook: Variant;
i: byte;
j, a: integer;
s, k, b, CustomAttrs: string;
begin
try
ExcelApp := CreateOleObject('Excel.Application');
MyWorkBook := CreateOleObject('Excel.Sheet');
except
on Exception do raise exception.Create('无法打开Excel文件,请确认已经安装Execl')
end;
MyWorkBook := ExcelApp.WorkBooks.Add;
MyWorkBook.WorkSheets[].Range['A1:D1'].Merge(True);
MyWorkBook.WorkSheets[].Range['A1:D2'].HorizontalAlignment := $FFFFEFF4;
MyWorkBook.WorkSheets[].Cells[, ].Value := Title;
with FDataSet do
begin
i := ;
for j := to FieldCount - do
begin
if Fields[j].Visible then
begin
b := Fields[j].DisplayLabel;
CustomAttrs := ';
if Assigned(FOnFormatCell) then
FOnFormatCell(Self, , i,
Fields[j].FieldName, CustomAttrs, b);
MyWorkBook.WorkSheets[].Cells[i, j + ].Value := b;
end;
end;
i := ;
Close;
Open;
First;
a := ;
while not Eof do
begin
for j := to FieldCount - do
begin
if Fields[j].Visible then
begin
CustomAttrs := ';
k := Fields[j].Text;
if Assigned(FOnFormatCell) then
FOnFormatCell(Self, i, a,
Fields[j].FieldName, CustomAttrs, k);
MyWorkBook.WorkSheets[].Cells[i, j + ].Value := k;
inc(a);
end;
end;
Inc(i);
Next;
end;
end;
s := 'A3:D' + IntToStr(i - );
s := 'A1:D' + IntToStr(i - );
MyWorkBook.WorkSheets[].Columns[].ColumnWidth := ;
MyWorkBook.WorkSheets[].Columns[].ColumnWidth := ;
MyWorkBook.WorkSheets[].Rows[].RowHeight := ;
MyWorkBook.WorkSheets[].Rows[].VerticalAlignMent := $FFFFEFF4;
MyWorkBook.WorkSheets[].Range[s].Font.Name := '仿宋';
s := 'A2:D' + IntToStr(i - );
MyWorkBook.WorkSheets[].Range[s].Borders.LineStyle := ;
MyWorkBook.WorkSheets[].PageSetup.CenterHorizontally := True;
MyWorkBook.WorkSheets[].PageSetup.PrintTitleRows := 'A1';
try
MyWorkBook.Saveas(FileName);
MyWorkBook.Close;
except
MyWorkBook.Close;
end;
ExcelApp.Quit;
ExcelApp := UnAssigned;
end;
end.
然后在调用它的单元里引用它就行了。
下面是调用它的代码:
procedure ToGetherExcel(NewData: TDataSet; NewString: string);
var
DataExcel: TDataSetToExcel;
saveDlg: TSaveDialog;
begin
saveDlg := TSaveDialog.Create(nil); //创建一个存储对话框
DataExcel := TDataSetToExcel.Create(nil);
try
saveDlg.Filter := 'Execl 文件(*.XLS)|*.XLS';
saveDlg.DefaultExt := 'XLS';
saveDlg.FileName := NewString;
if saveDlg.Execute then
begin
DataExcel.DataSet := NewData; //连接的数据集
DataExcel.DataSet.DisableControls;
DataExcel.Transfer(saveDlg.FileName, NewString);
DataExcel.DataSet.EnableControls;
AlterMesg('导出完毕', '提示信息');
end;
finally
saveDlg.Free;
DataExcel.Free;
end;
end;

先在程序上放上三个控件,TExcelApplication,TExcelWorkbook,TExcelWorkSheet,它们都在Server组件板上。
要控制Excel,就是采用自动化编程。以Excel作为自动化服务器。
首先,建立与自动化服务器的连接:
Excelapplication1.Connect;
Excelapplication1.Visible[]:=true;
Excelapplication1.Caption:='你要的标题';
ExcelWorkbook1.ConnectTo(Excelapplication1.Workbooks.Add(null,) );
Excelworksheet1.ConnectTo(Excelworkbook1.Worksheets[] as _worksheet) ; 然后就可以对Excel进行控件了:
从数据库导入数据:
Excel.cells.item[row,col]:=table1.field[i].value;
....
最后不要忘了断开连接
Excelapplication1.disconnect;
Excelapplication1.quit;
至今是delphi菜鸟 ****************************************************************** 如何把在dbgrid的指定几列导到excel表里?
我的做法:用listbox1显示dbgrid的所用供选择列,listbox2用来显示要导出的列:
procedure TForm1.FormCreate(Sender: TObject);
begin
if kadaoTable1.Active then
kadaoTable1.GetFieldNames(Listbox1.Items);
end;
procedure TForm1.addbitbtnClick(Sender: TObject);//选择字段
begin
try
if listbox1.Items.Count= then exit;
if listbox1.Selected[listbox1.ItemIndex] then
begin
Listbox2.Items.Add(Listbox1.Items[Listbox1.ItemIndex]);
Listbox1.Items.Delete(Listbox1.ItemIndex);
if Listbox2.Items.Count>= then
DeleteBitBtn.Enabled:=True;
end;
except
showmessage('你没有选择相应字段!');
end;
end;
procedure TForm1.DeleteBitBtnClick(Sender: TObject);//撤消选择
begin
try
if Listbox2.Items.Count= then exit;
if listbox2.Selected[Listbox2.ItemIndex] then
begin
Listbox1.Items.Add(Listbox2.items[Listbox2.itemindex]);
Listbox2.Items.Delete(Listbox2.itemindex);
end;
if Listbox2.Items.Count= then
DeleteBitBtn.Enabled:=False;
except
showmessage('你没有选择相应字段!');
end;
end;
procedure CopyDbDataToExcel(Args: array of const);
var
iCount, jCount: Integer;

begin
Screen.Cursor := crHourGlass;
if not VarIsEmpty(XLApp) then
begin
XLApp.DisplayAlerts := False;
XLApp.Quit;
VarClear(XLApp);
end;
try

except

Exit;
end; XLApp.WorkBooks.Add;
XLApp.SheetsInNewWorkbook := High(Args) + ;
for I := Low(Args) to High(Args) do
begin

if not TDBGrid(Args[I].VObject).DataSource.DataSet.Active then
begin

Exit;
end;

begin
CopyDbDataToExcel([DBGrid4]);
end;
我 想解决问题有两种办法:一、直接修改CopyDbDataToExcel。二、实现dbgrid4显示的字段列与listbox2中字段同步, dbgrid4中的其余字段要删除掉,不是隐藏。也就是用listbox2中字段来控制哪些字段导入到excel表中呀,如何实现呀? 请高手指点! ***************************** 将dbgrid中数据导出到excel后,如何编写程序使excel的列宽调整为最适合的列宽?

************************************************ 直接使用Excel对象,它是标准的COM对象,可以在Delphi中引用的。
我给你一个函数:
function ExportDataToExcel(cds: TClientDataSet; dbGrid: TDBGrid; ExcelAppData: TExcelApplication;
Title, strWhere: String): Boolean;
var
sheet,Range: Variant;
i,j: Integer;
str,fVal: String;

try
if ExcelAppData.Tag = then
begin
ExcelAppData.Disconnect;
ExcelAppData.Tag := ;
end;
ExcelAppData.Connect;
ExcelAppData.Visible[] := True;
ExcelAppData.Tag := ;
except
ShowMessage('启动Excel失败,Excel可能没有安装。');
Abort;
end;
cds.DisableControls;
try
if Trim(Title) = ' then Title := '查询结果';
ExcelAppData.Caption := Title;
ExcelAppData.Workbooks.Add(emptyparam,);
sheet := ExcelAppData.Workbooks[ExcelAppData.Workbooks.Count].Worksheets[]; sheet.name := Title;

if i < then i:=;

Range.Columns.Interior.ColorIndex := ; //设置表头的颜色
//计算表格区域
str := 'A3:' + str + IntToStr(cds.RecordCount + );
Range := Sheet.Range[str]; //取出表格数据区域边界
Range.Borders.LineStyle := xlContinuous; // 设置表格的线条
end;
Sheet.Cells[,] := strWhere;//'日期:' + DateToStr(Date);
//写表头
for j := to dbGrid.Columns.Count - do
begin
Sheet.Cells[,j + ] := dbGrid.Columns.Items[j].Title.Caption;
Sheet.Columns.Columns[j+].ColumnWidth := dbGrid.Columns.Items[j].Width div ;

cds.First;
for i:= to cds.RecordCount + do

Sheet.Cells[i,j + ] := fVal;
end;
cds.Next;
end;
Sleep(); //延时1秒,等待Excel处理完成

except on E: Exception do

ExcelAppData.Disconnect;
cds.EnableControls;
