Shortcode only outputs last result instead of every result

Hi,

I’ve created a shortcode to get the right data from the database. But I’m doing something wrong as I only get the last result instead of every result.

This is my code:

function holidaydata_func( $atts ) {
	$a = shortcode_atts( array(
		'country' => '',
		'year' => '',
	), $atts );
        $country = $a['country'];
        $year = $a['year'];
        
        global $wpdb;
        $tablename = 'table_name';
        $data = $wpdb->get_results($wpdb->prepare("SELECT country, country_eng, name_eng, week, remark, startdate FROM <code>$tablename</code> WHERE country = %s AND year LIKE %d ORDER BY startdate", $country, $year));
        $outputstart = '<table>';
        foreach ($data as $item) 
            {
                $output = '<tr><td>'.$item->name_eng.'</td></tr>';
            }
        $outputend = '</table>';    
        
        return $outputstart . $output . $outputend;
}
add_shortcode( 'holidaydata', 'holidaydata_func' );

So, this only results in one table row, instead of the multiple ones I should get.

What am I doing wrong here?

Thanks!
