DbGrid控件的标题栏弹出菜单
procedure TFrmOrderPost.DbgOrderPostMouseDown(Sender: TObject; Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
var
  CurPost:TPoint;

  GetCursorPos(CurPost);//获得鼠标当前坐标

//vCurRect该变量在DbGrid的DrawColumnCell事件中获得

如何将几个DBGRID里的内容导入同一个EXCEL表中？
在软件实际制作中，为节省开发成本和开发周期，一些软件人员通常会吧DBGrid中的数据直接导出到Excel表中，而先前能看到的函数仅仅只能在WorkBook的一个Sheet中导入数据，不支持多Sheet！。

单元应用：

Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls, DB, DBTables, Grids, DBGrids, ActiveX, ComObj,
Excel2000, OleServer;

测试环境：

　　OS：Win2k Pro；Excel2k；Delphi6.0

源程序：

功能描述：把DBGrid输出到Excel表格（支持多Sheet）
设计：CoolSlob
日期：2002-10-23
支持：CoolSlob@163.com
调用格式：CopyDbDataToExcel([DBGrid1, DBGrid2]);
}

procedure CopyDbDataToExcel(Args: array of const);
var
  iCount, jCount: Integer;
  XLApp: Variant;
  Sheet: Variant;
  I: Integer;
begin
  Screen.Cursor := crHourGlass;
  if not VarIsEmpty(XLApp) then
  begin
    XLApp.DisplayAlerts := False;
    XLApp.Quit;
    VarClear(XLApp);
  end;

  try
    XLApp := CreateOleObject(‘Excel.Application‘);
  except
    Screen.Cursor := crDefault;
  Exit;
  end;

  XLApp.WorkBooks.Add;
  XLApp.SheetsInNewWorkbook := High(Args) + 1;

  for I := Low(Args) to High(Args) do
  begin
    XLApp.WorkBooks[1].WorkSheets[I+1].Name := TDBGrid(Args[I].VObject).Name;
    Sheet := XLApp.Workbooks[1].WorkSheets[TDBGrid(Args[I].VObject).Name];

    if not TDBGrid(Args[I].VObject).DataSource.DataSet.Active then
    begin
      Screen.Cursor := crDefault;
      Exit;
    end;

    TDBGrid(Args[I].VObject).DataSource.DataSet.first;
    for iCount := 0 to TDBGrid(Args[I].VObject).Columns.Count - 1 do
      Sheet.Cells[1, iCount + 1] := TDBGrid(Args[I].VObject).Columns.Items[iCount].Title.Caption;

    jCount := 1;
    while not TDBGrid(Args[I].VObject).DataSource.DataSet.Eof do
    begin
      for iCount := 0 to TDBGrid(Args[I].VObject).Columns.Count - 1 do
        Sheet.Cells[jCount + 1, iCount + 1] := TDBGrid(Args[I].VObject).Columns.Items[iCount].Field.AsString;

      Inc(jCount);
      TDBGrid(Args[I].VObject).DataSource.DataSet.Next;
    end;
  end;

  XlApp.Visible := True;
  Screen.Cursor := crDefault;
end;

 怎样在DbGrid的左边，实现像EXCEL那样的自动编号？这些编号与表无关
unit Unit1;

      if (ARow>=1) and (ACol=0) then
         Canvas.TextRect(ARect,ARect.Left,ARect.Top,IntToSTr(ARow));
   end;

procedure TForm1.BitBtn1Click(Sender: TObject);
