Fix broken table generation

In 2c9922e8afc8f4b2d6d93b63dbfb865b139eac48 the code was optimised but
the order of method calls was incorrect, leading to several errors in
the test suite.

Not all the tests related to table generation got fixed, but at least
the component is not broken anymore.

Fixes symfony/symfony#26081
