procedure TForm10.DBGrid1DrawColumnCell(Sender: TObject; const Rect: TRect;
DataCol: Integer; Column: TColumn; State: TGridDrawState);
var Im1: TBitmap;
staff_id: string;
begin
Im1:=TBitmap.Create;
if (dm.AQ_personal.RecordCount = 0) then exit;
if Column.Field = dm.AQ_personal.FindField(‘autoid‘) then
// if Column.Field = dm.AQ_personal.FindField(‘工号‘) then
begin
with DBGrid1.Canvas do
begin
