方法如下:

1、创建一个普通Application。

2、在Form中分别放入ExcelApplication, ExcelWorkbook和ExcelWorksheet。

3、对Excel的一些操作,具体方法如下:

【打开Excel97】

    ExcelApplication1.Connect;

    ExcelApplication1.Visible[0]:=True;

【增加一个Workbook】

    ExcelWorkbook1.ConnectTo(ExcelApplication1.Workbooks.Add(EmptyParam,0));

【添加一个Worksheet】

  var  Temp_Worksheet: _WorkSheet;

  begin

    Try

      Temp_Worksheet:=ExcelWorkbook1.

      WorkSheets.Add(EmptyParam,EmptyParam,EmptyParam,EmptyParam,0) as _WorkSheet;//(注意)

      ExcelWorkSheet1.ConnectTo(Temp_WorkSheet);

    Except

      ShowMessage('Failure');

    End;

  end;

【关闭Excel】

    ExcelApplication1.Quit;

    ExcelWorksheet1.Disconnect;

    ExcelWorkbook1.Disconnect;

    ExcelApplication1.Disconnect;

【选择当前Workbook的某一Worksheet】

  procedure TForm1.ComboBox1DropDown(Sender: TObject);

  var

    i: Integer;

  begin

    ComboBox1.Clear;

    For i:=1 to ExcelWorkbook1.Worksheets.Count do

      ComboBox1.Items.Add((ExcelWorkbook1.Worksheets.Item[i] as _WorkSheet).Name);

  end;

  procedure TForm1.ComboBox1Change(Sender: TObject);

  begin

    ExcelWorkSheet1.ConnectTo(ExcelWorkbook1.Worksheets.Item [ComboBox1.ItemIndex+1] as _WorkSheet);

    ExcelWorkSheet1.Activate;

  end;

【选择某一Workbook】

  procedure TForm1.ComboBox2DropDown(Sender: TObject);

  var

    i: Integer;

  begin

    ComboBox2.Clear;

    if ExcelApplication1.Workbooks.Count >0 then

    For i:=1 to ExcelApplication1.Workbooks.Count do

    Combobox2.Items.Add(ExcelApplication1.Workbooks.Item[i].Name);

  end;

  procedure TForm1.ComboBox2Change(Sender: TObject);

  begin

    ExcelWorkSheet1.Disconnect;

    ExcelWorkBook1.ConnectTo(ExcelApplication1.Workbooks.Item[Combobox2.ItemIndex+1]);

    ExcelWorkBook1.Activate;

    ExcelWorksheet1.ConnectTo(ExcelWorkBook1.ActiveSheet as _WorkSheet);

    ExcelWorkSheet1.Activate;

  end;

【对某一单元格进行赋值及取值】

  procedure TForm1.Button5Click(Sender: TObject);

  begin

    ExcelWorksheet1.Cells.Item[SpinEdit2.Value,SpinEdit1.Value]:=Edit1.Text;

  end;

  procedure TForm1.Button6Click(Sender: TObject);

  begin

    Edit1.Text:=ExcelWorksheet1.Cells.Item[SpinEdit2.Value,SpinEdit1.Value];

  end;

【选择某一区域】

  ExcelWorkSheet1.Range['A1','C1'].Select;

【打开一个Excel文件】

  if OpenDialog1.Execute then

  Begin

      ExcelWorkBook1.ConnectTo(

         ExcelApplication1.Workbooks.Open(

            OpenDialog1.FileName,EmptyParam,EmptyParam,EmptyParam,

            EmptyParam,EmptyParam,EmptyParam,EmptyParam,EmptyParam,

            EmptyParam,EmptyParam,EmptyParam,EmptyParam,0));

      ExcelWorkSheet1.ConnectTo(ExcelWorkBook1.Activesheet as _Worksheet);

  End;

【存入一个Excel文件】

  procedure TForm1.button6Click(Sender: TObject);

  var

    i,row,column:integer;

  begin

    Try

      ExcelApplication1.Connect;

    Except

      MessageDlg('Excel may not be installed',mtError, [mbOk], 0);

      Abort;

    End;

    ExcelApplication1.Visible[0]:=True;

    ExcelApplication1.Caption:='Excel Application';

    ExcelApplication1.Workbooks.Add(Null,0);

    ExcelWorkbook1.ConnectTo(ExcelApplication1.Workbooks[1]);

    ExcelWorksheet1.ConnectTo(ExcelWorkbook1.Worksheets[1] as _Worksheet);

    Table1.Open;

    row:=1;

    While Not(Table1.Eof) do

    begin

      column:=1;

      for i:=1 to Table1.FieldCount do

      begin

        ExcelWorksheet1.Cells.Item[row,column]: =Table1.fields[i-1].AsString;

        column:=column+1;

      end;

      Table1.Next;

      row:=row+1;

    end;

  End;

【打印预览一个Excel文件】

  procedure TForm1.Button7Click(Sender: TObject);

  begin

    ExcelWorksheet1.PrintPreview;

  end;

【打印一个Excel文件】

  procedure TForm1.Button8Click(Sender: TObject);

  begin

    ExcelWorksheet1.PrintOut;

  end;

【说明】

  这些程序在Win98+Delphi 5+Excel 97下运行通过。这些例子还可以作适当的扩充,如DDE、执行宏调用、保存文件、打印文件及对Excel的设置等,其具体的实现及设置方法请参阅Microsoft Excel Visual Basic参考中的Microsoft Excel对象。
