敬请各位高手解决，DataGridView控件

Rem 如你的图，只有4列可以这么写。
Private Sub DataGridView1_CellEndEdit(sender As Object, e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellEndEdit
        Dim thisCol As Integer = 3

        Try
            If e.ColumnIndex = thisCol And DataGridView1.Rows(e.RowIndex).Cells(2).Value > 5 Then
                DataGridView1.Rows(e.RowIndex).DefaultCellStyle.BackColor = Color.Red
            Else
                DataGridView1.Rows(e.RowIndex).DefaultCellStyle.BackColor = Color.White
            End If
        Catch ex As Exception

        End Try
    End Sub
