[Vuejs]-Text only showing up in td element and not HTML

Try this:

<td v-html="ReplaceDashesInGlobalGroups(global.globalGroupName)"></td>

This should be rendered as HTML now instead of just plain text. Note this can open you up to XSS attacks.

Updates the element’s innerHTML. Note that the contents are inserted
as plain HTML – they will not be compiled as Vue templates. If you
find yourself trying to compose templates using v-html, try to rethink
the solution by using components instead.

Dynamically rendering arbitrary HTML on your website can be very
dangerous because it can easily lead to XSS attacks. Only use v-html
on trusted content and never on user-provided content.

In single-file components, scoped styles will not apply to content
inside v-html, because that HTML is not processed by Vue’s template
compiler. If you want to target v-html content with scoped CSS, you
can instead use CSS modules or an additional, global <style> element
with a manual scoping strategy such as BEM.
