TypeError: unsupported operand type(s) for +: 'float' and 'decimal.Decimal'

I am trying to extract a table from a random PDF file using explicit line, with the following table setting:

table_settings={
    "vertical_strategy": "explicit", 
    "horizontal_strategy": "explicit",
    "explicit_vertical_lines": (324, 444),
    "explicit_horizontal_lines": (333, 444),
}
im.debug_tablefinder(table_settings)

traceback:

Hi @Petru-Tanas-ProcessITCS. Appreciate your interest in the library. Please use the following table settings.

from decimal import Decimal

table_settings={
    "vertical_strategy": "explicit", 
    "horizontal_strategy": "explicit",
    "explicit_vertical_lines": (Decimal(324), Decimal(444)),
    "explicit_horizontal_lines": (Decimal(333), Decimal(444)),
}

im.debug_tablefinder(table_settings)

Thanks, @samkit-jain — that's the correct approach for the current codebase. I think, though, that it probably makes sense to auto-decimalize the values passed for those settings, so I'm reopening this issue and adding the enhancement label.

Added this enhancement, which is now available in v0.5.24. Thanks!
