Description

Hi,
I would like to retain an empty table row (<tr></tr>) but can not figure out the right combination of settings.

I tried to add tr to AutoFormat.RemoveEmpty.Predicate on the demo page but that does not work.

The actual use case is copy-pasting a table (fragment) form Excel or LibreOffice Calc with merged cells.
In this particular case the rowsapn attribute is added to all cells of the first row and hence the removal of the empty row results in an unwanted representation of the table as can be observed in the provided example above.

Any help is highly appreciated.

Research direction

Start with the linked demo configuration and the AutoFormat.RemoveEmpty.Predicate and AutoFormat.RemoveEmpty settings. Reproduce the supplied table with merged cells and rowspan attributes; done means the intentionally empty is retained without breaking the surrounding table structure.
