  begin
    Add;
    TjQGridDBColumn(IWjQDBGrid2.Columns[0]).FieldName := 'Client_Code';
    TjQGridDBColumn(IWjQDBGrid2.Columns[0]).Title    := 'Code';
    TjQGridDBColumn(IWjQDBGrid2.Columns[0]).Visible  := True;
  end;

  with IWjQDBGrid2.Columns do
  begin
    Add;
    TjQGridDBColumn(IWjQDBGrid2.Columns[1]).FieldName := 'Client_Name';
    TjQGridDBColumn(IWjQDBGrid2.Columns[1]).Title    := 'Name';
    TjQGridDBColumn(IWjQDBGrid2.Columns[1]).Visible  := True;
