How can I output the loop number of items in a table?

Table
Number | Title
1 | Title 1
2 | Title 2
3 | Title 3

Hi Randy

I have a custom shortcode that you can register for this:

/**
 * Add loop-iteration shortcode
 * 
 * Attributes
 * 'n' (optional) : test for nth iteration
 */
add_shortcode( 'loop-iteration', function( $atts ){

	global $loop_n;

	if ( !isset( $loop_n ) ) {
		$loop_n = 0;
		return $loop_n;
	}

	$loop_n++;

	if ( !isset( $atts['n'] ) ) {
		// no nth parameter, just return the current index
		return $loop_n;
	}
	else {
		$remainder = ( $loop_n + 1 ) % $atts['n'];
		return ( $remainder == 0 );
	}

});

It's a general purpose shortcode that can be used one of two ways.

Without any attributes it will simply output the current loop iteration.

With an 'n' parameter you can also use it inside conditional shortcodes to only show something every nth iteration, e.g.

[wpv-conditional if="( '[loop-iteration n='3']' eq '1' )"]
  <p>3rd item in loop</p>
[/wpv-conditional]

Thank you.
