vertically center a cell in a JQM table

vertically center a cell in a JQM table

Hello,

I use the JQM Table widget to make a table with two columns. The elements in the second column are higher than those in the first column, so, with the default top alignment, the result is not pretty. I would therefore like to vertically center the elements in the first column. I tried using CSS (vertical-align:middle), but this doesn't work. Is there a way to do it ?
