There are various ways of doing that.
Usually you have to scroll horizontally when the target contains huge tables. In iSiloX under "Properties:Tables", you can customize how you want the table formatting to be processed. Try to do this: "Properties:Tables:Process table formatting" and check "Include only tables at levels 1 or greater" (or replace 1 with a higher digit). Or try the second option, "Include only tables reachable up to 1 levels from the innermost tables". It depends on the target.
Another way, how you can definitely get rid of the horizontal formatting, is described here:

Note that I would always first try the first option since it displays output nicer. If you like, give me your target link and I will set it right.
