我正在使用自定义UI编辑器使用以下代码自定义Excel功能区:
<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui">
<ribbon startFromScratch="false">
<tabs>
<tab id="customTab" label="MyWorkbookTest">
<group id="customGroup1" label="Utilities">
<button id="customButton1" label="About" imageMso="ResultsPaneAccessibilityMoreInfo" size="large" supertip="View the framework version and status" onAction="ShowAbout" />
<button id="customButton2" label="Contact" imageMso="HyperlinkInsert" size="large" supertip="Launch the 'Contact Us' webpage" onAction="ShowContactUs" />
</group>
</tab>
</tabs>
</ribbon>
</customUI>
有谁能告诉我如何删除以红色圈出的部分自动出现?
