So I went and did a lot more reading and research and came across some verbage on creating a custom EAR file
I was told that this file would be a good place to start: bicustom-template.ear
I can see that it does have a lot of properties that can modify the overall look and feel of OBIEE, but within here I can not seem to find a property that would allow me to modify the default font size, for the contents of a table.
Would anyone know which file I should look at, or is it even possible to set a "default" font size for table results?
Agreed! there is no one-stop shop to change the global font changes, yet.
custom.ear is the best place to work on the font changes. There is a method to change the OOTB behavior ( view.css) , if you are so sure of what you are doing
