Fix data table pagination

[gwwar]

If we render a component, then rerender it with different defaultPageIndex and pageCount, we can see values like Page -2, Page -1, Page 0. The defaultPageIndex is also not respected when this value is updated.

Changes here:

• Update playground so we can see pager, set page size, and default index
• Component state only uses initial state on first render. To detect when defaults change, I use more component state to store initial state, and trigger related events when we detect these values have changed. An example would be updating defaultIndex
• I also expanded test coverage to catch these rerender cases.

Feel free to suggest alternatives, if folks can think of anything cleaner.

While testing I found an odd corner case for truncation. This is also present in main. I fixed this by doing a bounds check when setting offset.
