Row width changes using button in twitter bootstrap table -

i made stupid typo when typed put width instead of height!

i using buttons in each row of twitter bootstrap table. using table class table-condensed , button class btn-mini. problem when insert button height of row doubles. cannot find causing there appears no margin, padding or line-width attached button.

<table class="table table-condensed">     <tbody>         <tr class="span3">             <td class="span1">                 <button class="btn btn-mini">button</button></td>             <td class="span1">                 <button class="btn btn-mini">button</button></td>              <td class="span1">                 <button class="btn btn-mini">button</button></td>         </tr>     </tbody> </table> 

you can ignore class each cell divide total span of row according number of cells giving them equal widths.
