I was wondering if any of you managed to solve some of the issues that we face when dealing with a complex table in a pdf. For example several subheaders, cells that span several columns or rows (they can span several columns or rows, but their text would span only through 1 cell/row)

Was trying to find a solution to complex table using several libraries but so far always came a bit too short.
The library does pretty good at simplifying some of the basic tasks, but still a complex table seems to have no fix yet.

Below is an example table that I made on Excel inspired by a real case scenario that I have faced. Is there a way to fix the fact that some cells/headers span several columns for example. The only detection we have that would allow us to know for how many columns a header span is basically the horizontal line at the bottom of the header.
