How to fit a select tag in a table cell properly

Question

I am desperately trying to make a select tag fit in a table cell like it belongs there, not like someone wedged it in with a crowbar. Here is the code followed by the picture o

Answer 1

Play with the border of the select (this may or may not work in Safari)

select {
    border: 0;
    width: 100%;
}

Also instead of a lot of option onclick="JavaScript:quarterUpdate()" use select onchange"JavaScript:quarterUpdate()"... Inline Javascript like this shouldn't be used, you should do:

// jQuery
jQuery(document).ready(function($) {
    $('#isinz').on('change', quarterUpdate());
});
