I'm still getting to grips with render arrays and there similarity to FAPI arrays is a point of confusion. I'm customizing a node form using
hook_form_alter and I wanted to insert some custom markup in place of a field.
I have inserted a table render array as a child of a the field FAPI container array and much to my surprise the table was rendered. What's going on here?
How do I know when a render array will be processed properly?
