When using C-x C-- or C-x C-+ to change display font size, table heading becomes misaligned. I've tracked down the problem to
`org-table-separator-space` variable. The space inserted by it retains old size which skews alignment. Replacing it with " " via setq fixes it for a session. I tried to override it via `org-hook` and `orgtbl-mode-hook` but it somehow gets reset back to old value a first time I press C-c C-c to re-alight the table!
