Find first TD with text in a TR with JQuery

Question

I am using JQuery to iterate through all TRs in a table,

but not all rows have values in the first cell.

<TR>
  <TD>3</TD>
  <TD>2</TD>
  <TD>1</TD>
</TR>
  <TD></TD>
  <TD>3</TD>
  <TD>2</TD>
<TR>
</TR>
<TR>
  <TD></TD>
  <TD></TD>
  <TD>3</TD>
</TR>

How can i target the first TD in each row that is not empty and not just the first child?

Thanks!

Here's a simpler, more elegant solution:

$('tr').find('td:not(:empty):first').css('background', 'red');​

It just says in jQuery what you mean: "target the first td in each tr that is not empty".
