g.Drawline(colLeft,0,colLeft,g.Height)
g.Drawline(colLeft,g.Height,colLeft+colWidth,g.Height)
If Column=Me.ColumnCount-1 Then g.DrawLine(colLeft+colWidth-1,0,colLeft+colWidth-1,g.Height)
start=g.Height*.5
range=g.Height-start
For i As Integer=start To g.Height
g.ForeColor=RGB(0,0,0,(g.Height-i)/range*70+185)
g.DrawLine(colLeft,i,colLeft+colWidth,i)
