First of all, you need to make sure that specify this property for the table in the CSS

table-layout: fixed

Secondly, define this class in CSS

.fix-display-safari {
display: block !important;
}

then in Javascript/Typescript file, do the following

root.addClass("fix-display-safari");

root.removeClass("fix-display-safari", 100);

That way it would force the browser to recalculate DOM, and it would fix the width issue.
