The item module provides functionality for creating item tables.

Implemented templates

This module implements the following templates:

-- Item table
--
-- Creates various item tables from cargo queries.
--
--
-- Todo list
-- ---------
-- * Handle table columns that can have multiple cargo rows, preferably
--   in one or two queries. Not per column AND row.
-- * Handle template include size? Remove item link when getting close
--   to the limit?
-- * Add a wrapper around f_item_link to be able to disable all
--   hoverboxes, to avoid running into template expansion size issues.
