@xsduan The file saved as '.docx'. If I convert the word to 2007/2010, it will not report an error.
According to the changes made by your code, I can directly deal with this problem and thank you very much. However, your code reported "NameError: name 'InvalidXmlError' is not defined". I changed 'InvalidXmlError' to 'Exception'. So, is there good error to replace Exception? Thank you!

If you're having trouble extracting the data from a table, perhaps the following code can help you.
Fisrt is the quick monkey patch refer in https://github.com/python-openxml/python-docx/issues/547, It's part of the solution. If your table has a different number of cells per row, the problem persists.
You can refer this code:

data = []
try:
    for row in b.rows:
        for cell in row.cells:
            for paragraph in cell.paragraphs:
                data.append(paragraph.text)
except Exception as e:
    for tc in b._tbl.iter_tcs():
        cell = _Cell(tc, b)
        for b_tc in iter_block_items(cell):
            if isinstance(b_tc, Paragraph):
                data.append(b_tc.text)

def iter_block_items(parent):
    """
    Yield each paragraph and table child within *parent*, in document order.
    Each returned value is an instance of either Table or Paragraph. *parent*
    would most commonly be a reference to a main Document object, but
    also works for a _Cell object, which itself can contain paragraphs and tables.
    """
    if isinstance(parent, Document_c):
        parent_elm = parent.element.body
    elif isinstance(parent, _Cell):
        parent_elm = parent._tc
    else:
        raise ValueError("something's not right")

    for child in parent_elm.iterchildren():
        if isinstance(child, CT_P):
            yield Paragraph(child, parent)
        elif isinstance(child, CT_Tbl):
            yield Table(child, parent)

what is 'b' in that except block

from docx import Document
from docx.table import _Cell, Table

doc = Doument('your file')
for b in iter_block_doc:
    if isinstance(b, Table):
        ......

But what is the Document_c type? How can we import from the docx? Thank you.
