Bootstrap内联表单 - 如何使用固定的宽度/跨度？

Question

我有两行或多行，每行有三个复选框。我希望他们在行之间平均排列，就像他们在表格列中一样。现在他们看起来错开了，这取决于文本标签的长度。我如何模拟每行的表格列，以便布局看起来更加有组织？

<form id="form-filter" name="form-filter" method="POST" action="/filter" class="form-inline"> 
        <fieldset> 
        <legend style="margin-bottom:-10px;">Select up to 6 filters</legend> 
        <div class="control-group"> 
         <div class="controls"> 
         <label class="checkbox inline"> 
          <input id="Medjugorje" name="Medjugorje" type="checkbox" checked>Medjugorje 
         </label> 
         <label class="checkbox inline"> 
          <input id="Kibeho" name="Kibeho" type="checkbox">Kibeho 
         </label> 
         <label class="checkbox inline"> 
          <input id="Lourdes" name="Lourdes" type="checkbox">Lourdes 
         </label> 
         </div> 
         <div class="controls"> 
         <label class="checkbox inline"> 
          <input id="Fatima" name="Fatima" type="checkbox">Fatima 
         </label> 
         <label class="checkbox inline"> 
          <input id="Secrets" name="Secrets" type="checkbox">Secrets 
         </label> 
         </div> 
        </div> 
        <button type="submit" class="btn btn-primary">Filter</button> 
        <button id="clearButton" type="button" class="btn">Clear</button> 
        </fieldset> 
       </form>
