Description

I stumbled upon a performance issue with JQUI sortable with a table with quite many rows and columns. The initialization time of the Widget raised to seconds after some code change. I debugged and it seems the core issue is that the initialization raises up when some table rows are hidden.

I made a fiddle to show it: https://jsfiddle.net/z51kpc3L/4/

Compare the two different init times, depending on if 10 rows of the demo table are hidden or not: In this example, the init takes ~ 20ms and raises to ~30ms when 10 rows are hidden.
