I didn’t find if there is a way to include a table in a collapsed H2 header.
So far is possible to collapse a table OR collapse a header, but seems a table cannot be part of a collapsed header, just remains as his own collapsed content.
Was looking some posts this seemed possible with tables with no title, but so far seems every table need to have a title and so become an autonomous element.
This way is working thanks, even if seems it’s not straightforward: I select the table name, next drag and drop the table the very same position and next using tab allow me to fold in H2.
If I just select the table name and push Tab didn’t do anything.
Using Firefox last release if this is changing anything.
