Width options (`width`, `minWidth`, `maxWidth`) options are now a part of the core column object.
useBlockLayout and useAbsoluteLayout hooks now use this new internalized information to implement
their layouts. Those examples have been updated. A virtualized-rows example has also been added to
show off how the useBlockLayout hook can be used to virtualize rows with react-window.
* useAbsoluteLayout: To build tables with divs
* Adding `placeholderOf` attribute to column
* Adding `useAbsoluteLayout` in index.js
* Adding `useAbsoluteLayout` example
* Adding `useAbsoluteLayout` in api docs
* Adding test for `useAbsoluteLayout` hook
* TypeScript updates
I've found that trying to get solid TypeScript typings for this library
are a bit of a challenge. The composable nature of the library means
that the types for the builtin functions are by their nature somewhat
minimal, and that the user needs to be able to extend those interfaces
to reflect the specific plugins that are in use.
With that in mind I propose something like this.
To get the best out of them, you then need to extend those interfaces
using declaration merging, see
https://www.typescriptlang.org/docs/handbook/declaration-merging.html
e.g.
```ts
declare module 'react-table-hooks' {
export interface TableInstance<D = any>
extends UseFiltersValues<D>,
UsePaginationValues<D>,
UseExpandedValues,
UseGroupByValues {}
export interface TableState<D = any>
extends UsePaginationState,
UseGroupByState,
UseSortbyState<D>,
UseFiltersState<D> {}
}
```
This also puts the ability to extend those types with any user defined
hooks completely in the users hands.
This gives the greatest flexibility, but I'll admit that it isn't
particularly obvious. Perhaps a typescript readme and example is needed.
* fix useExpanded type
* fix module name
* fix typo
* address review feedback
* add IdType, update Filters definition
