Hi,
I have followed the step in the AEM 6.1 document to enable the table icons for my text component. It seems not effect.
https://docs.adobe.com/docs/en/aem/6-1/administer/operations/page-authoring/rich-text-edit or.html#Styles%20%28Tables%20and%20Table%20Cells%29
It always shows the default icon as the following screenshot.
Here is my node for the text component. I have created the rtePlugins node and table node and features property accordingly. Please help.
