Not sure what you mean. Could you explain a bit more, please?

Call this from within the cell renderer code:
getCellIndex().itemIndex

Don't know really, but I'm guessing it's got to do with the way the
DataGrid calculates its preferred height. Try setting the height
explicitly to a number if that works for you.

I think the text already gets cut off if it's too long to fit in the
cell, no? If you're talking about truncating it and then appending it
with an ellipsis ("..."), you need to use a custom cell renderer to
start with.
