Transaction Line Level HTML attribute doesn't print in the document designer output. On the transaction line Jet UI, I can see that HTML has a value populated (in my case a data table). But in the document designer output I can only see blank value for the same HTML attribute. PFB code used in the default function of HTML attribute.
