Unhandeled IndexError #243

Closed hantangantan closed 1 year ago

hantangantan commented 1 year ago

It is possible to delete the whole parameter table for P/Z and b,a, which results in an IndexError:

Traceback (most recent call last):
  File "C:\dev\python\pyfda\pyfda_venv\Lib\site-packages\pyfda\input_widgets\input_coeffs.py", line 940, in _delete_cells
    self.refresh_table()
  File "C:\dev\python\pyfda\pyfda_venv\Lib\site-packages\pyfda\input_widgets\input_coeffs.py", line 606, in refresh_table
    self.ba[1][0] = 1.0  # restore a[0] = 1 of denominator polynome
    ~~~~~~~~~~^^^
IndexError: index 0 is out of bounds for axis 0 with size 0

Reproduce:

Start pyfda Select b,a or P/Z tab (leftside) Select all cells (rows and columns) Klick on Delete Button (next to clear button)
