On lines 237-238, the Javascript is using Jquery to lookup UI elements by id (the $('#' ... ) bits), and then setting the values you are looking for using the .html(...) function -- so the values must be coming from the function inside there, namely language.get("TABLEVALUE",1)
If you put a breakpoint in your JS source at the start of that switch statement on line 232, then you might be able to see more about the language object and trace the data back to the actual ajax request that retrieved it. I'd look closer at that "English.txt" call 3 lines down from the one you have highlighted (since the language you have chosen is English). More likely, that is some UI text strings, but SOMEWHERE in this stack there is data being returned in text format, so it can be shown inside the table... good luck!
