how to read out the column labels of DataTables

[nnako]

Hi,

is there a way to read out the column labels of an existing DataTable? The labels can be set e.g. via <DataTable>.add_column() or <DataTable>.add_columns(), but reading them out does not seem obvious to me. The documentation mentions an attribute <DataTable>.columns, but it just says it would be a dict accessed by the ColumnKey and providing a Column with no further explanation than mentioning "metadata".

Using <DataTable>.get_row_at(0) returns the 1st data row, not the respective column names.

As it doesn't seems possible to set breakpoints within a textual application, single-step debugging and probing does not seem to be possible.

Is there any help on
- the particular question about DataTable column label determination?

Or some hints about how to debug more easily?

Ok, found a solution, which is a bit complex, I think:

column_names = []
for _i in range(len(self.get_row_at(0))):
    _coord = Coordinate(row=0, column=_i)
    _row_key, _column_key = self.coordinate_to_cell_key(_coord)
    column_names.append(self.columns[_column_key].label)

where self references the DataTable object.
