The data displayed in the table is given as an argument to `view`. To put that another way, the `Table.State` value only tracks the details specific to *displaying* a sorted table, not the actual data to appear in the table. **This is the most important decision in this whole library.** This choice means you can change your data without any risk of the table getting out of sync. You may be adding things, changing entries, or whatever else; the table will never &ldquo;get stuck&rdquo; and display out of date information.

The trick is that all these simple functions are defined in terms of crazier ones that allow for more customization. As the user **NEEDS** that complexity, they can read on and gradually use the parts that are relevant to them. This means the user never finds themselves in a situation where they have to learn a bunch of stuff that does not actually matter to them. At the same time, that stuff is there when they need it.

To turn this into advice about API design, **helper functions can make a library simpler to learn and use.** Ultimately, people may not use `Table.floatColumn` very often in real stuff, but that function is crucial for learning. So when you find yourself with a tough API, one way to ramp people up is to create specialized helper functions that let you get common functionality without confronting people with all the details.
