I've read some Q&A about centering some text inside a div but for some reason the examples I try are not working for me. I'm using some jquery-ui and jquery-mobile css libraries but I don't think that is my problem. The "blue button" seems to align vertically in the middle just fine. But why don't the two text columns?
Here is the jsfiddle link: http://jsfiddle.net/Thread7/tstwwt9p/

<div class="ui-grid-b" style="display: table;width: 100%;border-style: solid;">
<div class="ui-block-a" style="text-align:center;">
<button style="color:#000;background-color:#00b2ee" class="ui-btn ui-shadow ui-corner-all" type="button">Blue Button</button>
</div>
<div class="ui-block-b " style="text-align:center;display: table-cell;">Middle Column Text</div>
<div class="ui-block-c" style="text-align:center;"><a href="#" class="ui-link">Sample Link Text</a></div>
</div>
