第一列为自动序号，可在绑定的datatable中添加一列，把序号加进去.
第二列颜　可以用下面代码实现
    for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
dataGridView1.Rows[i].Cells[0].Style.BackColor = Color.FromName(dataGridView1.Rows[i].Cells[1].Value.ToString());
}

datagridview在绑定的前提下，怎样设置第一列自动添加序号，第二列单元格颜为数据的对应的颜
可能没说清楚，数据源里的第二列的值为red，blue等字符，datagridview的第二列的单元格的颜则为相应的颜，而不是显示red,blue等字符

this.dataGridView1.RowPostPaint += new DataGridViewRowPostPaintEventHandler(dataGridView1_RowPostPaint);

this.BuildColor();
}
private void dataGridView1_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
{
datagridview数据源// 行号
SolidBrush B = new SolidBrush(Color.Black);
e.Graphics.DrawString((e.RowIndex + 1).ToString(), e.InheritedRowStyle.Font, B, e.RowBounds.Location.X + 20, e.RowBounds.Location.Y + 4);
