添加行列可参考如下代码：

from pptx import Presentation
from pptx.table import _Cell
import copy
prs = Presentation('t1221.pptx')
TAB = prs.slides[1].shapes[1].table
copy_idx=0
insert_idx=0
new_row = copy.deepcopy(TAB._tbl.tr_lst[copy_idx])
for tc in new_row.tc_lst:
    cell = _Cell(tc, new_row.tc_lst)
    cell.text = 'foobar'
TAB._tbl.append(new_row)
new_col = copy.deepcopy(TAB._tbl.tblGrid.gridCol_lst[-1])
TAB._tbl.tblGrid.append(new_col)  
# for tr in TAB._tbl.tr_lst:
#     # duplicate last cell of each row
#     new_tc = copy.deepcopy(tr.tc_lst[-1])
#     tr.append(new_tc)
#     # cell = _Cell(new_tc, tr.tc_lst)
#     # cell.text = 'bar'
prs.save('t1221.pptx')
