Change column width bootstrap tables

I have a static PHP site I'm using Bootstrap on. The tables are controlled by Bootstrap.

I've noticed that I have seemingly no control over the lengths of the TD sections so that I can prevent the phone numbers, etc..., from wrapping. As you can see there is plenty of space on the end, just don't know how to spread that space out.

I tried inline widths on the <th> but nothing happens:

  <table class="table table-condensed table-striped  table-hover">
  <thead>
    <tr>
        <th>#</th>
        <th width="12%">Last Name</th>
        <th width="12%">First Name</th>
        <th width="12%">Spouse's Name</th>
        <th width="20%">Address</th>
        <th width="5%">City</th>
        <th  width="12%"class="did_phone">Phone</th>
        <th width="15%">E-Mail</th>
         <th width="15%"></th>
    </tr>
  </thead>
  <tbody>

So... how does one change the <td> widths, make adjustments so there is no wrapping, in Bootstrap?
