<p>Even though we strongly encourage you to write custom breakpoints yourself, the framework includes a single pre-configured breakpoint that targets the stacked style to smaller phones and swaps to a tabular prsentation on larger phones, tablet and desktop devices. To use this preset breakpoint, add the <code>ui-responsive</code> class to the table to convert from the stacked presentation to a tabular presentation at 560px (35em). If this breakpoint doesn't work for your content, we encourage you to write a custom breakpoint as descibed above.</p>

<p>It's fairly common to need to logically group multiple columns together under a heading group for financial or scientific data. The framework can support the most simple version of this by allowing for two rows of table headers (<code>TH</code>), with the first row containing simple <code>colspan</code> attributes to group the columns below. In this configuration, the framework will add a class to the label of the first cell in each group to allow you to style these differently and provide additional visual hierarchy.</p>
