Question

i have table for quiz results, in the table there a cell for grade.

Example (cell grade is in a while loop and the numbers appears after checking the other cells with if):

    <table border="1">
      <tbody>
        <tr>
          <th> id </th>
          <th> question </th>
          <th> answer </th>
          <th> correct answer </th>
          <th> grade </th>


        </tr>

        <tr>

          <td> 1 </td>
          <td> question how bla bla bla</td>
          <td> bla bla answer</td>
          <td> correct answer</td>
          <td> 5 (this cell has the grade of each question)</td>
        </tr>
        <tr>

          <td> 2 </td>
          <td> question2 how bla bla bla</td>
          <td> bla bla answer2</td>
          <td> correct answer2</td>
          <td> 8 (this cell has the grade of each question)</td>
        </tr>

etc

// in this cell i want to show me the average from td grade

<td colspan="4" align="center">average</td>
  <td><input type="text" readonly="readonly" name="Avg" /></td>      


      </tbody>
    </table>

see this tut http://www.amitpatil.me/table-manipulation-with-jquery/ What You are probably looking for is mentioned in the 5th point on above page ie “5) Find all the values from td of particular column “

$(".grid tr").each(function(i){
   colValues[i] = $('tr:nth-child('+(i+1)+')>td:nth-child(1)').html();
});
