I've added the CSS config from old vCenter 7 to the vCenter 8 UI by using Tampermonkey:

// ==UserScript==
// @name         Recover nowrap in vCenter
// @namespace    http://tampermonkey.net/
// @version      2025-08-01
// @description  Recover nowrap in vCenter
// @grant        GM_addStyle
// @include *
// ==/UserScript==



(function() {
    //'use strict';

    GM_addStyle('clr-dg-cell { white-space: nowrap; overflow: hidden; text-overflow: ellipsis }');
})();
