Module:AbilityTableGive feedback

This module exposes two functions.

render generates a table of hero abilities matching a named list, and is invoked via {{AbilityTable}}.
is_member(list, ability_key, ability_num) is a shared function that decides whether a single ability belongs to a list (applying the same properties and exclusions); it is used both internally by render and externally by Module:AbilityHints, so the ability-hint icons always stay in sync with these tables.

Template:AbilityTable — the template that invokes this module
Module:AbilityTable/Lists — defines which properties each list matches on, and which abilities to exclude
Module:AbilityTable/Notes — editor-authored notes displayed in the Notes column
Module:AbilityTable/ComplexRenderers — custom column renderers for lists that need more than just Notes
Module:AbilityHints — reuses is_member to render interaction-hint icons on ability cards

-- Module:AbilityTables
-- Renders sortable wikitables of abilities filtered by a named stat.
-- Backing module for Template:AbilityTable.
--
-- Usage on wiki pages: {{AbilityTable|charges}}

-- ============================================================
-- ADDING A NEW STAT
-- ============================================================
-- 1. Add an entry to friendly_to_internal mapping the friendly
--    name (lowercase) to the internal AbilityData property keys
--    that determine whether an ability appears in the table.
--
-- 2. Optionally add a matching entry to extra_columns to show
--    additional data columns beyond Hero and Ability.
--    Copy the "charges" block as a template:
--      - headers: list of column names shown in the table header
--      - get_cells: function(ability) that returns a table of
--        { ["Column Name"] = value } for a single ability row.
--        Return nil or omit a key to show "—" in that cell.
--    If no extra_columns entry is added, only Hero and Ability
--    columns are shown.
-- ============================================================

-- Used to filter which abilities appear in the table.

-- Optional extra columns for each stat.
-- Each entry has:
