I can't get underline to show for @click links in DataTable

[leemthai]

I use links generated with @click quite a lot in my app. The default is to show with underline.

But when I add them inside a DataTable, these same links are not underlined it seems.
It's only when I hover over the link does the underline appear, and that is due to:

link-style-hover

link-style, link-color, link-background appear to be ignored for @click links inside a DataTable.

Is there something special about how DataTable handles the CSS for links?

Thanks,
