We’ve just released a new version of Tabulator which now has a mutator option if you’re using its app_tables mode.
That allows you to define a callable which will take a data tables row and ‘mutate’ it to something else for use in the tabulator.
It’s particularly useful if you’re using the persistence module from Anvil Extras. You get all the benefits of lazy loading from anvil.tables.app_tables along with the ability to define and use your own custom objects!
