推荐答案

您需要处理 CellPainting 事件，并用所需的颜色填充背景，例如与 GridColor相同的颜色，然后通过将绘制区域限制为不包含分隔线的矩形来执行其余绘制:

You need to handle CellPainting event and fill the background with desired color, for example the same color as GridColor, then perform the rest of painting by limiting the paint area to a rectangle excluding divider:

private void DataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
    if (e.RowIndex == -1)
    {
        var dgv = (DataGridView)sender;
        var r = e.CellBounds;
        var w = 0;
        if (e.ColumnIndex > -1)
        {
            w = dgv.Columns[e.ColumnIndex].DividerWidth;
            r.Width = r.Width - w;
        }
        e.Graphics.SetClip(r);
        e.Paint(r, DataGridViewPaintParts.All);
        e.Graphics.SetClip(e.CellBounds);
        if (w > 0)
        {
            r = new Rectangle(r.Right - 1, r.Top, w + 1, r.Height);
            using (var brush = new SolidBrush(dgv.GridColor))
                e.Graphics.FillRectangle(brush, r);
        }
        e.Handled = true;
    }
}

例如，如果将列的 DividerWidth 设置为10，并将 GridColor 设置为 Color.Red ，则可以使用以下方法获得以下结果:上面的代码:

For example, if you set DividerWidth for the columns to 10 and set GridColor to Color.Red you can get the following result using above code:
