主题：[求助]如何设置窗口表空白区透明？

 呃，没你说的问题。不然你就这样写

Dim tb As Table = e.Form.Controls("Table1").Table
Dim grid As C1FlexGrid.C1FlexGrid = tb.Grid
grid.BackColor = Color.Transparent
grid.Styles.Alternate.BackColor =  Color.White
grid. Styles.EmptyArea.BackColor = Color.Transparent
tb.DataTable.AddUserStyle("a", Color.White, Color.Black)
tb.AllowEdit = True

或者drawcell这样写

e.Table.DataTable.AddUserStyle("b", Color.red, Color.Black)
If e.Row.Index Mod 2 = 0 Then
    e.Style = "a"
Else
    e.style = "b"
End If
