selector - Need JQuery to select a table only if its 1st row has more than 1 column -


I have to select and work with a table object with jQuery, but only when it is less than with one There is less one row column. The following selector works, but I find only one way: 

  $ ('# my_table_is: has (tr.)'). DoSomething ();

The successes I have tried have no success: 

  $ ('# my_table_id: has (tbody & gt; tr & gt; Td: eq (1)) '). Do something (); $ ('# My_table_id: is (TD tr: nth-child (1))'). DoSomething (); . $ ('# My_table_id: (TD: eq (1))') DoSomething ();

What combination of selector and filter will this work?

BTW, I need this reason that the tableer with a multi-column sort list will apparently blow when the table output only has 1 column.

How about checking a good wetting?
