```
 var app_name = "example_text"
         jq('.table_name > tbody:last').append(
            '<tr><td>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</td><td>app_name</td><td><button class="removeb">Remove</button></tr>'
         );

```

How do I use the var in .append() to as a substitute? Thanks!! Can I use %s, or is there another way of doing it in javascript? Thanks!
