It is possible to reinitialize a table widget ?

[TrueMisterJeanP]

Hello,

I Will know if is it possible to change the headings of a table widget after having initialized it.

First:

self.table1 = toga.Table(
headings=[],
data=[],
style=Pack(flex=1),
on_select=self.on_select_row_handler
)

That produce a empty table and it is what I want.

Next:
To change the headings and the data i use this code but below it does not work:

    self.table1.headings = ['one', 'two']
    self.table1.data = [('1','2')]

It is possible to reinitialize a table widget ?

Thank you for your help.

Thanks for the report. Is changing column headers currently possible? No - the API doesn't provide for changing column headers. Should it be possible? Yes. If you wanted to make an API proposal to make this possible, I'd be in favour.

The ability to add columns was added in #820; #2011 modifies this to insert and remove columns.
