Ulrich reported this bug via email. It is caused by the bug fixing of Bug_0136, so it only exists on V2.05.
In V2.05, if a table element has only one row, and the row is painted as table header, then an error will occur when runing the simulation.
The bug will be fixed in next update. Meanwhile there is a workaround: add a new row with a space charactor in the table content.
