Hide row if it contains empty columns

Question

I have a table with a couple of rows, each row with two columns, the first column will hold title and second column will have the respective values.sometimes, cells in the right

Answer 1

Your selector will cause the if statement never to be true for any row in your example. $("td:not(:empty)") always selects the element with the title, so length is always 1. if(!1) is never true.

You should remove the double negative (the ! and the :not) to make it clearer, and then check that the length (i.e. number of matched elements) is > 0.
