# DataTables Integration - COMPLETE ✅

**Date**: 2025-01-20
**Status**: Ready for Production
**All Tests**: PASSING ✅
**All Linting**: PASSING ✅

## Summary

Integrated Simple-DataTables library into the
lf-releng-project-reporting HTML reports, providing sorting, searching,
and pagination features for tables.

## Issues Resolved

### Issue 1: Config Undefined Error

**Problem**: `'config' undefined` error in template
**Root Cause**: Jinja2 macros don't inherit parent template variables
**Solution**: All macros now accept `config` as explicit parameter

### Issue 2: Template Syntax Error

**Problem**: `expected token 'end of statement block', got 'with'`
**Root Cause**: Invalid Jinja2 syntax mixing `include` with parameters
**Solution**: Set parameters as variables before `{% include %}`

## Implementation Complete

{% macro datatables_js(config) %}
{% macro datatables_classes(config, enable_datatables=None, ...) %}
```

### Usage Pattern

```jinja2
{# In base.html.j2 #}
{% import 'html/components/datatables_support.html.j2' as datatables %}
{{ datatables.datatables_css(config) }}
{{ datatables.datatables_js(config) }}

{# In section templates #}
<table class="dt-enabled">  <!-- Full features -->
<table class="dt-enabled dt-no-search dt-no-pagination">  <!-- Sorting -->

{# In components #}
{% set enable_search = false %}
{% set enable_pagination = false %}
{% include 'html/components/data_table.html.j2' %}
```
