What is the maximum number of elements a list can hold?

Answer: 
didnt get ya completely but to append a new tr to a specific tr you can use 

```
$('#trUniqueId').append(
      $('<tr/>').attr("id","newtrId")
);

```
Alfred is correct, your question is very vague.

However, to add a new row (newID) after the existing row (uniqueID), use the following code:

$('#uniqueID').after('<tr id="newID">' + CELL CONTENT + '</tr>');

As for pulling in the information via Ajax, we'll need to see code samples.
