Long story short - in Kirby2 “tablex” plugin was working good. Now wanted to use similar table in Kirby 3 panel. Added Table field | Kirby but it does not work as expected. If in cell stored text with whitespaces, after save & reload table is messed up. One of solution was wrap each cell text in quotes, but it does not work always.
Therefore decide to switch to Structure | Kirby which seems very similar to table.
