PrettyTable.add_rows method support divider Argument

[jingfeihu]

Is your feature request related to a problem? Please describe.

It's not friendly to add section divider when I add multi rows to table.

1.Current Implement:

table = PrettyTable()
table.field_names = [...]
for row in rows1:
    table.add_row(row , divider=((rows1.index(row) == (len(rows1) - 1)))
for row in rows2:
    table.add_row(row , divider=((rows2.index(row) == (len(rows2) - 1)))
...
for row in rowsx:
    table.add_row(row , divider=((rowsx.index(row) == (len(rowsx) - 1)))
print(table)

2. I hope to implement like this:

table = PrettyTable()
table.field_names = [.......]
table.add_rows(rows1, divider=True)
table.add_rows(rows2, divider=True)
...
table.add_rows(rowsx, divider=True)
print(table)

Describe the solution you'd like

Solution1: Setting divider while add_rows.

    def add_rows(self, rows, section_divider=False) -> None:
        for row in rows:
            per_row_divider = ((rows.index(row) == (len(rows) - 1)) and (section_divider == True))
            self.add_row(row, divider=per_row_divider)

Describe alternatives you've considered

Solution2: Setting divider while add_row or add_rows is finished. Allow user to access self._divider by index.

table.dividers()[index] = True
table.dividers()[index] = False
