Hi @cschloer,

have I missed something?

Hi @cschloer,

I've created a hook for [email protected] to support head/body checks for the same class:

def test_validate_wide_table_with_order_fields_issue_368(log):
    @check('custom-check', type='custom', context='body')
    class CustomCheck(object):
        def __init__(self, *args, **kwargs):
            pass

        def check_headers_hook(self, cells, sample):
            errors = []
            errors.append(Error('custom-check-head'))
            return errors

        def check_row(self, cells):
            errors = []
            errors.append(Error('custom-check-body'))
            return errors

    report = validate([['header'], ['value']], checks=['custom-check'])
    assert log(report) == [
        (1, None, None, 'custom-check-head'),
        (1, None, None, 'custom-check-body'),
    ]
