Table panel does not scroll headers

Hi,
I have included a table panel in my dashboard. After some tweaking it seems to export data nicely, but the column names don’t follow when I scroll the table horizontally.
The table has so many columns that the horizontal scroll is enabled, all the values scroll but the headings of the columns are fixed - which totally breaks the logic of the data.

Any idea of how to fix this?

Thanks
Helge

I am also looking for a fix for this issue. Is there a solution available in any version greater or equal to 6.3.5?
