Expose columnProps in RAC Cell

[sebald]

Hey,

I know that the RAC component should cover most cases and we should reach for the hooks if we want more customization, but I found that a lot of common features (e.g. column alignment, striped columns, ...) are enable by exposing the properties of the columns to cell in the same column.

Internally the TableCell already has access to the collection. Exposing the respective column of a cell should be straight forward (happy to submit a PR!)

react-spectrum/packages/react-aria-components/src/Table.tsx

Line 1135 in 48f29e1

cell.column = state.collection.columns[cell.index];

Passing something like the state.collection.columns[cell.index].props as columnProps to a render function (via values) would greatly improve the versatility of the Table component.

(Context: I tried to use the TableStateContext, but the cell doesn't know its own index.)

Not sure if this is a good idea anymore. The <Table> actually can get the state when using a function with className or style. So maybe, for consistency reasons, this is also possible to do for the other table related components.

Any updates on this? I'd also like to add styling props to Column that can be shared with Cell — like React Spectrum does with align and showDivider.
