Add Table configs for header/footer size and default cells options

[mperrando]

Hi @veej.

Is it possible to add to the customisation of the header also the Icon of the hint?

const HintIcon = config.headerHintIcon ?? IconInfo
...
<HintIcon size={12} color="currentColor" />

maybe the whole element?

{config.headerHintElement ?? <IconInfo size={12} color="currentColor" />}
