Update tables.less

iOS doesn't pick up the z-indexing properly on the dropdowns unless you
specify one for the parent navbar.

Fixed Table cell sizing with multiple classes by using *= instead of ^=

`.table` style is duplicate in `List groups in panels` and `Tables in panels`

fix typo

Add background-color to carousel.

Navigation arrows were aligned to the top of page. Vertically centered them in this fix.

Set a background color for the carousel example so that white text is now legible. Also fixed typo on line 97.
