Column Width - too wide for fixed area

I've got three columns in my table and it works fine until I place links within the <td></td> tags. For some reason it adds extra space in the 3rd spot on the row. Same thing with images placed in there. Instead of all this extra space creating a new line it continues past the boundaries of my fixed width and makes the whole table width get longer and longer. What do I do to get the table to stop doing this? Here is my HTML.

<style type="text/css" title="currentStyle">
@import "/v/vspfiles/templates/stationary/css/DataTables_page.css";
@import "/v/vspfiles/templates/stationary/css/DataTables_table.css";
