HTML5 data-* attributes - cell data

DataTables can use different data for different actions (display, ordering and searching) which can be immensely powerful for transforming data in the display to be intuitive for the end user, while using different, or more complex data, for other actions. For example, if a table contains a formatted telephone number in the format xxx-xxxx, intuitively a user might search for the number but without a dash. Using orthogonal data for searching allows both forms of the telephone number to be used, while only the nicely formatted number is displayed in the table.

One method in which DataTables can obtain this orthogonal data for its different actions is through custom HTML5 data attributes. DataTables will automatically detect four different attributes on the HTML elements:

• data-sort or data-order - for ordering data
• data-filter or data-search - for search data

This example shows the use of data-sort and data-filter attributes. In this case the first column has been formatted so the first name has abbreviated, but the full name is still searchable (search for "Bruno" for example). Additionally, although the last column contains non-numeric data in it, the column will correctly order numerically as the data-sort / data-order attribute is set on the column with plain numeric data.
