Answer 1

首先在Uses处加上ComObj

procedure TForm1.Button1Click(Sender: TObject);
var h,k:integer;
Excelid: OleVariant;
s: string;
begin
try
Excelid := CreateOLEObject('Excel.Application');
except
Application.MessageBox('Excel没有安装！', '提示信息', MB_OK+MB_ICONASTERISK+MB_DEFBUTTON1+MB_APPLMODAL);
Exit;
end;
try
ADOQuery1.Close;
ADOQuery1.SQL.Clear;
ADOQuery1.SQL.Add('select * from jj_department');
ADOQuery1.Open;
k:=ADOQuery1.RecordCount;
Excelid.Visible := True;
Excelid.WorkBooks.Add;
Excelid.worksheets[1].range['A1:c1'].Merge(True);
Excelid.WorkSheets[1].Cells[1,1].Value :='部门编码表' ;
Excelid.worksheets[1].Range['a1:a1'].HorizontalAlignment := $FFFFEFF4;
Excelid.worksheets[1].Range['a1:a1'].VerticalAlignment := $FFFFEFF4;
Excelid.WorkSheets[1].Cells[2,1].Value := '组别编号';
Excelid.WorkSheets[1].Cells[2,2].Value := '公司编号';
Excelid.WorkSheets[1].Cells[2,3].Value := '组别名称';
Excelid.worksheets[1].Range['A1:c1'].Font.Name := '宋体';
Excelid.worksheets[1].Range['A1:c1'].Font.Size := 9;
Excelid.worksheets[1].range['A1:c2'].font.bold:=true;
Excelid.worksheets[1].Range['A2:c2'].Font.Size := 9;
Excelid.worksheets[1].Range['A2:c2'].HorizontalAlignment := $FFFFEFF4;
Excelid.worksheets[1].Range['A2:c2'].VerticalAlignment := $FFFFEFF4;
h:=3;
ADOQuery1.First;
while not ADOQuery1.Eof do
begin
Excelid.WorkSheets[1].Cells[h,1].Value := Adoquery1.FieldByName('Fdept_id').AsString;
Excelid.WorkSheets[1].Cells[h,2].Value := Adoquery1.FieldByName('Ffdept_id').AsString;
Excelid.WorkSheets[1].Cells[h,3].Value := Adoquery1.FieldByName('Fdept_name').AsString;
Inc(h);
Adoquery1.Next;
end;
s := 'A2:f'+ IntToStr(k+2);
Excelid.worksheets[1].Range[s].Font.Name := '宋体';
Excelid.worksheets[1].Range[s].Font.size := 9;
Excelid.worksheets[1].Range[s].Borders.LineStyle := 1;
Excelid.Quit;
except
Application.MessageBox('导入数据出错！请检查文件的格式是否正确！', '提示信息', MB_OK+MB_ICONASTERISK+MB_DEFBUTTON1+MB_APPLMODAL);
end;
MessageBox(GetActiveWindow(), 'EXCEL数据导出成功!', '提示信息', MB_OK +MB_ICONWARNING);

end;
