Drop styling. Developers will apply their own theme anyways.
$value = html_entity_decode($value, ENT_COMPAT, 'UTF-8'); $value = htmlspecialchars($value);
I would instead suggest to use Piwik_DataTable_Filter_SafeDecodeLabel to keep this logic in one place only.
Note: dataTable.html is a proof-of-concept; in practice, the data would be embedded in the page from the server-side so that token_auth is not exposed in the page source
