TYPO3 Core

In EXT:rtehtmlarea/res/contentcss/default.css the selectors to align text in table cells (th and td) are missing. They should actually look like this:

p.align-left, td.align-left, th.align-left, ... { text-align: left; }
p.align-center, td.align-center, th.align-center, ... { text-align: center; }
p.align-right, td.align-right, th.align-right, ... { text-align: right; }
p.align-justify, td.align-justify, th.align-justify, ... { text-align: justify; }

Otherwise, in an out-of-the-box installation, hitting the alignment buttons shows no effect on td's and th's
