如何在运行时（.Net Framework 4.0）设置datagridview列的边框样式？

Question

我有一个绑定到数据源的只读datagridview。 它有两列。 现在，我希望第一列没有单元格边框样式； 第二个具有“全部”（即，单元的所有侧面均应具有边框）作为单元的边框样式。 在将datagridview绑定到数据源之前，我正在编写如下所述的内容，但是它没有任何效果。 假设有问题的列名为DisplayName。

Dim newStyle As New DataGridViewAdvancedBorderStyle()
With newStyle
.Top = DataGridViewAdvancedCellBorderStyle.Single
.Left = DataGridViewAdvancedCellBorderStyle.Single
.Bottom = DataGridViewAdvancedCellBorderStyle.Single
.Right = DataGridViewAdvancedCellBorderStyle.Single
End With

DisplayName.CellTemplate.AdjustCellBorderStyle(newStyle, newStyle, True, True, True, True)

请更正或提出更好的方法。 问候。

Private Sub dgvLegends_CellPainting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellPaintingEventArgs) Handles dgvLegends.CellPainting
    'Draw custom cell borders.
    'If current column is DisplayName...
    If dgvLegends.Columns("DisplayName").Index = e.ColumnIndex AndAlso e.RowIndex >= 0 Then
            Dim Brush As New SolidBrush(dgvLegends.ColumnHeadersDefaultCellStyle.BackColor)
            e.Graphics.FillRectangle(Brush, e.CellBounds)
            Brush.Dispose()
            e.Paint(e.CellBounds, DataGridViewPaintParts.All And Not DataGridViewPaintParts.ContentBackground)

            ControlPaint.DrawBorder(e.Graphics, e.CellBounds, dgvLegends.GridColor, 1, ButtonBorderStyle.Solid, dgvLegends.GridColor, 1, ButtonBorderStyle.Solid, dgvLegends.GridColor, 1, ButtonBorderStyle.Solid, dgvLegends.GridColor, 1, ButtonBorderStyle.Solid)

        e.Handled = True
    End If
End Sub

尝试CSS？

    .style1 
    {
        border:none;
        width: 100%;
    }
    .style1 td+td
    {
        border:1px solid red;
    }

 <table cellpadding="2" class="style1">
    <tr>
        <td>a
            &nbsp;</td>
        <td>d
            &nbsp;</td>
    </tr>
    <tr>
        <td>b
            &nbsp;</td>
        <td>c
            &nbsp;</td>
    </tr>
