Why does pad_edge=False allow for an extra character in cell?

[kmvanbrunt]

I'm seeing unexpected behavior with the pad_edge Table setting.

In the following code, setting pad_edge to False allows for one extra character beyond the specified Column width.

from rich import print

table_1 = Table(Column(width=5), Column(width=5), show_header=False, pad_edge=False)
table_1.add_row("123456", "123456")
print(table_1)

Output

┌───────┬───────┐
│123456 │ 123456│
└───────┴───────┘

Expected Output:

┌──────┬──────┐
│1234… │ 1234…│
└──────┴──────┘

If I set pad_edge to True, the expected truncation occurs.

from rich import print

table_2 = Table(Column(width=5), Column(width=5), show_header=False, pad_edge=True)
table_2.add_row("123456", "123456")
print(table_2)

Output

┌───────┬───────┐
│ 1234… │ 1234… │
└───────┴───────┘

Why does setting pad_edge to False allow this extra character? Is this a bug or is it by design?
