I'm after using a date-time field within a table cell. I suspect it requires a plugin to make this happen - has anyone done this?
So to make more cell types possible I ended up copying the complete Table Field code from Craft core into my plugin.
Someone might ask what this is good for, you could use Matrix instead! Sure, but sometimes you're in the need for another hierarchy level or you'd simply opt for the cleaner, more compact view of a table field for your date or time inputs.
