Support ol / ul elements inside td element and li inside ol / ul

Problem/Motivation

Need to support ol / ul and li in tables.

Steps to reproduce

This table markup:

	<table class="table table-bordered table-responsive">
		<caption class="text-left"><span class="small lead">For example, your year productive capacity is 601 acres of grain</span></caption>
		<thead>
			<tr>
				<td></td>
				<th class="text-right" scope="col">Reference year 0</th>
				<th class="text-right" scope="col">Reference year 1</th>
				<th class="text-right" scope="col">Reference year 2</th>
			</tr>
		</thead>
		<tbody>
			<tr class="text-right">
				<th scope="row">Grain (acres)</th>
				<td>601</td>
				<td>601</td>
				<td>601</td>
			</tr>
			<tr class="text-right">
				<th scope="row">Industry Benchmark</th>
				<td>$130.12</td>
				<td>$79.11</td>
				<td>$124.78</td>
			</tr>
			<tr class="text-right">
				<th scope="row">Total</th>
				<td>$78,074</td>
				<td>$47,460</td>
				<td>$74,870</td>
			</tr>
		</tbody>
		<tfoot>
			<tr>
				<td colspan="4">
				<ol class="list-unstyled">
					<li>Average ($78,074 + $47,460 + $74,874) ÷ 3 = $66,802</li>
					<li>Multiplied by 0.44% = $298</li>
					<li>Multiplied by 71% = $211</li>
					<li>Total: fee amount = $211</li>
					<li>Add: administrative cost share = $56</li>
					<li>Total: fee plus administrative cost share = $267</li>
				</ol>
				</td>
			</tr>
		</tfoot>
