Dim newStyle As New DataGridViewAdvancedBorderStyle()
With newStyle
.Top = DataGridViewAdvancedCellBorderStyle.OutsetDouble
.Left = DataGridViewAdvancedCellBorderStyle.OutsetDouble
.Bottom = DataGridViewAdvancedCellBorderStyle.OutsetDouble
.Right = DataGridViewAdvancedCellBorderStyle.None
End With

Dim newStyle1 As New DataGridViewAdvancedBorderStyle()
With newStyle
.Top = DataGridViewAdvancedCellBorderStyle.OutsetDouble
.Left = DataGridViewAdvancedCellBorderStyle.None
.Bottom = DataGridViewAdvancedCellBorderStyle.OutsetDouble
.Right = DataGridViewAdvancedCellBorderStyle.OutsetDouble
End With

Me.DataGridView1.Rows(1).Cells(1).AdjustCellBorderStyle(newStyle, newStyle, False, False, False, False)
Me.DataGridView1.Rows(1).Cells(2).AdjustCellBorderStyle(newStyle1, newStyle1, False, False, False, False)

唔唔~我面临你一样的问题！好像AdjustCellBorderStyle也只是对整列进行边框设置！！！~~~~
