supposing you have a table generated via php from a mysql database,
eg,
<?php do { ?>
<tr>
<td><?php echo $row_sampleOA_set['concentration']; ?> </td>
</tr>
<?php } while ($row_sampleOA_set = mysql_fetch_assoc($sampleOA_set)); ?>
how would you go about using the contenteditable attribute to make the table cell editable and the edit to update the database?
