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")
);

```
Try this 

```
$(‘ tblDoc tr:last’).after(

 "<tr><td  style=’width:150px;’>value1</td><td  style=’width: 150px’>value2</td><td  style=’width: 150px’></td></tr>"

);

```
