I could implement this myself, but would be better if Datatable had it by default

Additional context

Hey Jiri!
Not much free time at the moment, but this should be fairly easy to implement, so I guess I could do it later tonight.
Would you consider adding a title attribute sufficient, or were you thinking about a Mantine Tooltip?

[capaj]

I was thinking mantine tooltip but title might work too

[icflorescu]

I find Mantine's Tooltip a bit too intrusive in this context, so let's go with title.
Should be fixed in a couple of minutes in v.1.7.31, as soon as the build pipeline runs.
