is there a way to make field style bold in a table?

[reyservicenow]

is there a way to make   field style bold in a table? i have tried putting:

font-weight:bold;

for the style field and does not make it bold any suggestions? i have also tried other scripts that make CSS style bold.

i have tried a client script on load and grabbing the sysID also. any suggestions ?

In searching for a solution for this same issue, I'd like to share a solution I came up with because the font-weight: bold didn't work for me either!
I used a text shadow to replicate bold: text-shadow: 0.5px 0.5px #3C59E7;
The hex number is my attempt at a match at the blueish/purple color of the text in the Next Experience.
