default_cell_formatter() in DataTable formats float to 2-digit scale, which is often undesirable.

Code

textual/src/textual/widgets/_data_table.py

Line 197 in db3fda9

content = f"{obj:.2f}"

This defaults all floats to be in 2-digit scale. I think it would be better to change this to simple float-to-str conversion, so that the user can decide the scale. If there is a specific reason to limit the float type scales, the scale should be left to maximum to the limits.

@grvstick It likely was a virus.

The original plan was to expose this function to end users, but that never came to fruition. Hopefully DataTable can get a bit of love soon to give more control over things like this 😄
