改成比如
'创建一个"授权表",对各表及其中各列进行"可视化"和"允许编辑"的授权:
For Each t As Table In Tables
t.Visible = True
t.AllowEdit = True
For Each c As Col In t.Cols
c.Visible = True
c.AllowEdit = True
Next
Next
Tables("授权表").Visible = (User.Type <> UserTypeEnum.User )
If User.Type = UserTypeEnum.User Then
For Each dr As DataRow In DataTables("授权表").Select("用户名 = '" & User.Name & "'" )
If Tables.contains(dr("表名")) Then
If dr.IsNull("列名") Then
Tables(dr("表名")).Visible = Not dr("不可见")
Tables(dr("表名")).AllowEdit = Not dr("不可编辑")
Else
Tables(dr("表名")).Cols(dr("列名")).Visible = Not dr("不可见")
Tables(dr("表名")).Cols(dr("列名")).AllowEdit = Not dr("不可编辑")
End If
End If
Next
End If
