Improve integration with Profiler, actions & collection column types

[Kreyu]

• Actions created by the ActionsColumnType now contains a valid reference to their data table
• Columns created by the CollectionColumnType now contains a valid reference to their data table, and each nested column is now named by their index (0, 1, 2, etc.) instead of generic __name__
• Two new data table events - PRE_INITIALIZE and POST_INITIALIZE
• Completely overhauled integration with Symfony Profiler

I can't seem to use CollectionColumnType:

            ->addColumn('rifeProgramFrequencies', CollectionColumnType::class, [
                'entry_options' => [
                    'formatter' => function (RifeProgramFrequency $rifeProgramFrequency): string {
                        return $rifeProgramFrequency->getFrequency();
                    },
                ],
            ])

            ->addColumn('rifeProgramFrequencies', CollectionColumnType::class, [
                'entry_options' => [
                    'formatter' => function (RifeProgramFrequency $rifeProgramFrequency): string {
                        return $rifeProgramFrequency->getFrequency();
                    },
                ],
            ])

Hey @nicodemuz, try setting a property path inside the entry_options that will direct the bundle on which property should be displayed:

 ->addColumn('rifeProgramFrequencies', CollectionColumnType::class, [
     'entry_options' => [
         'property_path' => 'frequency',
     ],
 ])

Because the CollectionColumnType creates "fake" columns inside itself for each entry in the collection, the property path will default to column name, which in this case would be 0, 1, 2, etc. (index of each entry).

The formatter callback is applied on the data retrieved from the entity, so it's later in the process. Alternatively, you can use the getter instead of property path:

 ->addColumn('rifeProgramFrequencies', CollectionColumnType::class, [
     'entry_options' => [
         'getter' => function (RifeProgramFrequency $rifeProgramFrequency): string {
             return $rifeProgramFrequency->getFrequency();
         },
     ],
 ])
