We have a requirement not to show required icon for required fields.  So, in normal section, we handled in Skin rule to handle this scenario. Below is the post we referred for this fix.  "https://collaborate.pega.com/question/how-change-required-asterisk-after-label-some-other-text".

We are not able to achieve for Table section. Asterisk is shown in table section. Kindly let us know if you have handled similar scenario. 

Thanks in Advance.
