Sort by Column

[Bryanna]

Hi! I am trying to sort my table matrix by the most recent date in the beginning of the table and the older date further to the right.  When I try to sort by column and select the date nothing happens. When I try to select within the visual i cant sort by the date. What am i missing to be able to sort?

your screenshot is too blurry to be helpful. What's the column format for your header column?
