Views table borkage

Thanks, yeh, those settings are fine, and haven't changed. I'm going to need to wander through the settings recently made in other modules. I just wondered if this had been seen before. I started with D6, back in the day,  and haven't! 

Found it thanks to your hints...I had shot my own foot trying to clean up PHP errors about nulls when exhausted.

So for anyone else, here is my view_view_table that works:

function vhb_bootstrap_preprocess_views_view_table(&$variables) {

$view = $variables['view'];

// We need the raw data for this grouping, which is passed in as $variables['rows'].

// However, the template also needs to use for the rendered fields. We

// therefore swap the raw data out to a new variable and reset $variables['rows']

// so that it can get rebuilt.

// Store rows so that they may be used by further preprocess functions.
