Table block

Hi,

I’m trying to add a custom Table block (columns, rows…). The defaults structure should be something like this:

$defaults = array(
	'title' => '',
	'columns' => array(
		1 => array(
			'title' => 'Column 1 heading',
			'rows' => array(
				1 => array( 'content' => 'Row 1 content'),
				2 => array( 'content' => 'Row 2 content'),
				3 => array( 'content' => 'Row 3 content')
			)
		),
		2 => array(
			'title' => 'Column 2 heading',
			'rows' => array(
				1 => array( 'content' => 'Row 1 content'),
				2 => array( 'content' => 'Row 2 content'),
				3 => array( 'content' => 'Row 3 content')
			)
		)
	)
);

When I add the block into the builder, the default data are filled just fine. However, when I save the template, it seems like the rows data are not retained (the column title is there – working). I have text inputs for the rows and their id’s are this:
<?php echo $this->get_field_id('columns') ?>-<?php echo $column_count ?>-rows-<?php echo $row_count ?>-content

Is it possible to have this structure at all?

Thanks!
