This is meant to mitigate an issue with table alignment when those tables are
results of source blocks, contain links in cells and are hidden (i.e., folded):
in those circumstances, the table alignment seems to be broken, because the cell
width does not take into account that links are shorter than their textual
representation.
I am not quite sure whether this is a bug in my configuration or a bug in Org
mode itself. The function to compute cell width is `org-string-width`, but
maybe this function does not get passed the correct input when tables are folded
and need to be aligned?
