Hi Frits,

Please add the below custom code (How to add custom code?)

add_filter( 'woosc_get_table_minimum_columns', function () {
    return 1;
} );

And all empty columns will be hidden https://www.screencast.com/t/ALiFN6sJ

OR

Please add below CSS code to WP-Admin → Appearance → Customize → Additional CSS:

.woosc-area .woosc-inner .woosc-table .woosc-table-inner .woosc-table-items table tbody tr.tr-image td.td-placeholder {
    background-image: none;
}
.woosc-area .woosc-inner .woosc-table .woosc-table-inner .woosc-table-items table tbody tr td.td-placeholder:before {
    display: none;
}

All empty columns still be kept but haven't the background https://www.screencast.com/t/2TYePpyE
