how to add a list to a table's rows

[l1t1]

I have a list of many rows that need to be append to a table, I try to do as follwing and failed

>>> list2=[['1','2','3'],['4','5','6']]
>>> table.add_row(list2[0])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "D:\Python312\Lib\site-packages\rich\table.py", line 465, in add_row
    raise errors.NotRenderableError(
rich.errors.NotRenderableError: unable to render list; a string or other renderable object is required

if I use join method, all columns is inserted into the first column

table.add_row(",".join(list2[0]))

[l1t1]

I solved it with table.add_row(*list2[0])
