Question

How would I grab text from a td inside a table and insert it to the first td in the same row? –using jQuery

<table border=1>
  <tbody>
    <tr>
      <td>APPEND TEXT1 HERE</td>
      <td></td>
      <td>GRAB TEXT1 HERE</td>
    </tr>
    <tr>
      <td>APPEND TEXT2 HERE</td>
      <td></td>
      <td>GRAB TEXT2 HERE</td>
    </tr>
    <tr>
      <td>APPEND TEXT3 HERE</td>
      <td></td>
      <td>GRAB TEXT3 HERE</td>
    </tr>
  </tbody>
</table>

Answer 1

$('table td:first-child').text(function(){
    return $(this).siblings().last().text()
})

In case that you want to append the text(instead of replacing):

$('table td:first-child').text(function(i, c){
    return c + ' ' + $(this).siblings().last().text()
})
