ReadTheDocs theme has an annoying bug of text not being wrapped insid…

…e table cells. Each row is extended to fit the text as a single line. For a table with multiple columns and long sentences the table may get wide, with long scrollbar underneath and is not convenient to read. This MR makes the text wrap inside table cells. There is an open PR to fix this issue - readthedocs/sphinx_rtd_theme#432.
