推荐答案

您需要加入代码到 CellPainting 事件处理程序做一些风俗画。对于电池边框设置为无，使用 CellBorderStyle ：

You need to do a little custom painting by adding code to the CellPainting event handler. For setting the cells border to None, use CellBorderStyle:

dataGridView1.CellBorderStyle = DataGridViewCellBorderStyle.None;

// CellPainting event handler for your dataGridView1
private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
    if (e.RowIndex == -1 && e.ColumnIndex > -1)
    {
       e.Handled = true;
       using (Brush b = new SolidBrush(dataGridView1.DefaultCellStyle.BackColor))
       {
         e.Graphics.FillRectangle(b, e.CellBounds);
       }
       using (Pen p = new Pen(Brushes.Black))
       {
         p.DashStyle = System.Drawing.Drawing2D.DashStyle.Dash;
         e.Graphics.DrawLine(p, new Point(0, e.CellBounds.Bottom-1), new Point(e.CellBounds.Right, e.CellBounds.Bottom-1));
       }
       e.PaintContent(e.ClipBounds);
    }
}
