with support for left padding so it can be embedded in a list.

I'm using it like this:

<?PHP
function quizDrawLinesToMatch( $headerLeft, $headerRight, $rows )
{
	echo '1. Draw lines to match the following:' . PHP_EOL . PHP_EOL;;
	$columns = [$headerLeft, $headerRight];
	$t = new TextTable( $columns, $rows );
	echo $t
		->setAlgin( [ 'L', 'R'] )
		->setLeftPad( 1 )
		->setLeftPadStr( "\t" )
		->render();
}

quizDrawLinesToMatch( 'Item'	, 'Description', [
	['```<h6>```'		,  'paragraph' ],
	['```<table>```'	,  'table row' ],
	['```<p>```'		,  'table' ],
	['```<tr>```'		,  'heading' ],
	['```<td>```'		,  'table data' ]
	] );
?>

Output:

1. Draw lines to match the following:

	| Item          | Description |
	|:------------- | -----------:|
	| ```<h6>```    | paragraph   |
	| ```<table>``` | table row   |
	| ```<p>```     | table       |
	| ```<tr>```    | heading     |
	| ```<td>```    | table data  |

And the preview of the output:

1. Draw lines to match the following:

   Item	Description
   <h6>	paragraph
   <table>	table row
   <p>	table
   <tr>	heading
   <td>	table data
