function matrix_handler_field_field::render_item in Matrix field 8.2

Same name in this branch

1. 8.2 views/views_handler_field_field_matrix.inc \matrix_handler_field_field::render_item()
2. 8.2 src/matrix_handler_field_field.php \Drupal\matrix\matrix_handler_field_field::render_item()

Render all or part of the matrix according to the settings.

Matrix bundles the entire table into the first item/delta slot so this function only get's called once and is passed a render array.

Assuming you use the default formatter of course! Alternative formatters aren't going to work here. So beware!
