Wouldn't the solution be to make the data table as wide as it needs to be and use the OS horizontal scrollbar to access the rightmost columns?
It probably breaks the right side of the page grid layout but if there are many columns to see, the ability to see them should grant an exception. I made that choice a few times with my customers. They wanted to see the data in those pages, as if they were in Excel.
