Update Table row not valid in for loop when using 'break'

[Time-Coder]

Such that table is a instance of tables.Table
This code works fine:

for row in table:
    row["col"] = value
    row.update()

This code will not have any effect on current table:

for row in table:
    row["col"] = value
    row.update()
    break # because of this line

You can test by:

for row in table:
    row["col"] = value
    row.update()
    print(row["col"])
    break

for row in table:
    print(row["col"])
    break

It will print different result.
