作用，点击datagridview表格中的checkbox 列，来控制其他列是否显示“已审核”

       private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)  //根据checkbox值的不同，进行审核和存储。
        {
            if (e.ColumnIndex == 0)
            {
                if ((string)(this.dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex]).Tag == "0")
                {
                    this.dataGridView1.Rows[e.RowIndex].Cells[8].Value = "已审核";
                    (this.dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex]).Tag = "1";
                }
                else if ((string)(this.dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex]).Tag == "1")
                {
                    this.dataGridView1.Rows[e.RowIndex].Cells[8].Value = "";
                    (this.dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex]).Tag = "0";
                }
            }
            
        }
