宽高在这里设置

selCon.Size = new Size(node.Bounds.Width*1.25, node.Bounds.Height)

颜色这里设置

label.BackColor = Color.Red
label.ForeColor = Color.Yellow

你去下载开发版的地方，下载一个商业版安装后，就可以打开.table的文件了。

Dim sender As Object = Args(0)
Dim e As Object = Args(1)
'绘制文本和底色
        Dim nodeFont As Font = e.Node.NodeFont
        If nodeFont Is Nothing Then
            nodeFont = DirectCast(sender, System.Windows.Forms.TreeView).Font
        End If

        If (e.State And System.Windows.Forms.TreeNodeStates.Selected) <> 0 Then
            e.Graphics.FillRectangle(Brushes.Lime, e.Node.Bounds)  '背景色
            e.Graphics.DrawString(e.Node.Text, nodeFont, Brushes.Red, e.bounds.x, e.bounds.y+10)  '字体色
        Else
            Dim a1 As SolidBrush = New SolidBrush(e.Node.TreeView.BackColor)
            e.Graphics.FillRectangle(a1, e.Node.Bounds)  '背景色
            e.Graphics.DrawString(e.Node.Text, nodeFont, Brushes.Black, e.bounds.x, e.bounds.y+10)  '字体色
        End If
