Listbox heading and default values

Hi all.

I filed a bug report about not being able to properly add default header values or rows to a weblistbox.

Since this is still present in the latest beta, I wonder what others do to handle this problem or if I am the only one who can
reliably reproduce this bug. The only workaround I know is to add two columns, add the default values and then remove the second column.
That’s the only way I can add a listbox header default and cell values in the IDE. Do you know other ways?
