[BUG] rich.table.Table._get_padding_width() forgets to account for self.pad_edge

[mgedmin]

• [x] I've checked docs and closed issues for possible solutions.
• [x] I can't find my issue in the FAQ.

Describe the bug

When you create a rich.table.Table() with columns that have fixed widths and set that table's pad_edge=False, the first and the last columns get extra padding on the right side. The first column gets left padding's worth of extra space, but places it on the right. The last column gets right padding's worth of extra space.

import io

import pytest
from rich.console import Console
from rich.table import Column, Table


@pytest.fixture
def output() -> io.StringIO:
    return io.StringIO()


@pytest.fixture
def console(output: io.StringIO) -> Console:
    return Console(
        width=60,
        file=output,
        force_terminal=True,
        legacy_windows=False,
        color_system=None,
        _environ={},
    )


def test_table_with_fixed_column_widths(
    console: Console, output: io.StringIO
) -> None:
    table = Table(
        Column('verb', width=5),
        Column('noun', width=5),
        Column('wh', width=2),
        box=None,
        pad_edge=False,
        expand=False,
        show_header=True,
    )
    table.add_row('hello', 'world', 'oh')
    console.print(table)
    assert output.getvalue().rstrip('\n') == '\n'.join([
        'verb   noun   wh',
        'hello  world  oh'
    ])

I will create a pull request, once I figure out how to create pull requests properly (#3882 is the one I'm currently attempting, but I can't run the tests locally without unrelated failures, and GitHub CI is still waiting for maintainer's approval).
