I wanted to customize my default font by `(custom-set-faces '(default
((t(:family "Ubuntu")))))`. Then, after `M-x org-table-create` the TAB
started creating a cell to the left of the one it should have jumped to
(see a video here (webmd video of the screencast):
https://u.pcloud.link/publink/show?code=XZVXhe0Z2K8AAQBKOwQH7uE7LkNtHYGlHQTy
). The expected behaviour is that TAB only jumps to the next cell,
without creating additional ones. The actual behaviour is, depending on
the family font used, it does create an additional cell. Not every
font causes the unexpected behaviour.

I made a list of all fonts I have installed in my machine (shell
`fc-list -b` and then get the text in "family"), and tested if
they caused the TAB to behave unexpectedly or not. The results are here
(org file):
https://u.pcloud.link/publink/show?code=XZbXhe0ZptNoWfCjJc7bKxFCXyzTgzNKdDsV
. 34 of the 173 fonts I have installed fail (cause the unexpected
behaviour).
