主题：数据表和管理项目被禁止了

If User.Type<>UserTypeEnum.Administrator Then
    RibbonTabs("Table").Visible = False
    RibbonTabs("Project").Visible = False
    RibbonTabs("Other").Groups("Execute").Items("SQLExecute").Enabled = False
    RibbonTabs("Other").Groups("Execute").Items("Command").Enabled = False
Else
    RibbonTabs("Table").Visible = True
    RibbonTabs("Project").Visible = True
    RibbonTabs("Other").Groups("Execute").Items("SQLExecute").Enabled = True
    RibbonTabs("Other").Groups("Execute").Items("Command").Enabled = True
End If
