To set a different column width for the Ship to, add this to your functions.php
:
add_action( 'admin_head', 'wpse_237354_ship_to_column' );
function wpse_237354_ship_to_column() {
global $pagenow;
if ( $pagenow == 'edit.php' ) {
?>
<style type="text/css">
.manage-column.column-shipping_address {
width: 10px;
}
</style>
<?php
}
}
This adds custom CSS in the header page with your new column width. Just change width: 10px
to your new size.
