Dear Maintainer,

Calligra Words doesn't even see tables in RTFs as tables. I had to
switch to AbiWord to get the table to not just show up as a bunch of
text soup.

Calligra Sheets also won't display axis labels when opening a fairly
basic ODS exported by Google Sheets. I switched in the first place
because I became frustrated with its seeming inability to label bars
in bar charts diagonally.
