Refa: <Table>

[sebald]

The following things should be improved on the <Table> component:

• Use <Checkbox> refa: <Table> #2081
• Switching between a cell with data and a cell with a checkbox should not be decided in the <TableCell>. We should rather have two dedicated Cells. refa: <Table> #2081
• Keyboard Focus is always shown refa: <Table> #2081
• Remove align props, this can be done via styling refa: remove align prop from Table #2036
• Make the cell with the checkbox a separate part for styling?
• Is cell spacing correct? refa: <Table> #2081
• Make nested columns work refa: <Table> #2081
• disabling rows doesn't work works ... react-aria documentation isn't correct :D
• visually support sorting #2107
