Column headers in the interactive table

Hello everybody,

I am experiencing a little problem on the interactive table when I shift columns.

The headers (so the properties) are built in the following way : headerLine1
headerLine2
headerLine3.

Then I get my headers on 3 different lines which is what I want.

However when I am moving a column to the right for example then the
tag appears!

This is also the case if I go to the next page (as the interactive table is included in a paged table), but I solved this case by replacing "
" by "\n".

My problem is I don't know how to catch the column shifting event to rename the headers.

Thanks for your help!
