Sometimes you wish to have a class to identify views tables. But currently views does not provide such a class attribute in the <table> element.
So there's an issue about that in https://drupal.org/node/1689472.
In #20 cybercampbell mentions a workaround solution until it is clear, if this will be solved in views too. I think it is worth mentioning it as a snippet:
function THEME_preprocess_views_view_table(&$vars) {
$vars['classes_array'][] = 'table';
}?>
and if you want striped tables:
function THEME_preprocess_views_view_table(&$vars) {
$vars['classes_array'][] = 'table table-striped';
}
?>
That's still some more code to write, but until a fix it provides a lot of flexibility.
Did you try it out?
