One of the columns is a URL. org-mode is hanging while exporting the table. It does not seem to crash, but it is taking a significant amount of time. The worst part is that it does not appear to be linear. 80 rows -> 17 seconds 160 rows (same 80 rows duplicated) -> 58 seconds 160 rows, 8 columns -> 21 seconds (it seems to not matter which columns there are). I wonder if this is expected behaviour. Given that org does not sort the tables, why does the time increase non-linearly to the size of the table? If interested, I can make the table available. thanks a lot! --daniel -- Daniel M.
