If you check out this JS fiddle: http://jsfiddle.net/DE5Bp and try to sort the Tariff column which I want to sort by the first digit e.g the minutes.
How can I solve this issue?
You can see I have tried to trick the plugin with the <span class="hide">
although this hasn't solved the issue.
UPDATE: http://jsfiddle.net/6jAyF/ this version forces the sorter:"integer"
