Yes, the table is set up to be used for Dungeons and Dragons character creation. If you're using a different game system or using the table for characters to write stories about, you'll have to make adjustments.
You can't make changes to the online spreadsheet, but you're free to copy it and make whatever adjustments you like. I'd appreciate links back, if you post a changed table, so that I can see how the little thing is getting on in the world.
