[O] links cause table misalignment

[Thomas P]

Hello,

With org-mode 9.1.9, my tables sometimes become misaligned when I press TAB and the cursor is in a cell with a link. 

In an org-mode buffer, enter:

| aa | aa |

| [[a][a]] | |

The lower-left cell becomes misaligned when I press TAB and the cursor is on the link "a". 

I get no misalignment with org-mode 8.2.10.

emacs-version: GNU Emacs 25.3.2 (x86_64-pc-linux-gnu, GTK+ Version 3.18.9) of 2017-09-12

Regards,

Thomas
