How to create ShortCode

Hi @mabufoysal

This is how you will be able to create a shortcode.

add_shortcode( 'logo_showcase', 'wpsupport_logo_showcase_func' );
function wpsupport_logo_showcase_func( $atts ) {
    $atts = shortcode_atts( array(
        'id' => ''
    ), $atts, 'logo_showcase' );

    // Do something
    $html = "<h2>Hello Word!</h2>"
 
    return $html;
}

N.B. Showing shortcode in wp list table is another question or another task
