Support geopandas tables

Bug / Issue
Possibly a bug, or a known limitation. I am working with geodataframes and wish to upload these as browsable tables. However on attempt I get errors:
table = dp.DataTable(gdf) # gdf is geopandas.geodataframe.GeoDataFrame
report = dp.Report(table)
report.upload(name='gis_table')
.
.
.
ArrowTypeError: ('Did not pass numpy.dtype object', 'Conversion failed for column geometry with type geometry')
Probably related to pyarrow, see here:

Yep, this is related pyarrow, which is the underlying format we use to store dataframes. A workaround may be to use dp.Table instead of dp.DataTable, but unfortunately this won't be interactive.
We'll look at what we can do to improve support for geodataframes going forwards and update the docs accordingly.
