Check if cell content contains specific shape

Question

I have a table that contains some text with upper line, the upper line changes the meaning of the text, I want to be able to determine for each cell if it contains a line shape or not.

From what I saw, there's a cell.part.inline_shapes but it gives the same results for each cell in the table, and it the doesn't specify the actual shape (line/rectangular/square etc.).

e.g. in the following table, only cell [1, 0] is containing line

def is_line(shape):
    #TODO implement
    pass

def is_containing_line(cell):
    # TODO: check if shape is in current cell, as cell.part.inline_shapes are the same in every table cell    
    cell_shapes = cell.part.inline_shapes
    return any(is_line(shape) for shape in cell_shapes)


[i for i, cell in enumerate(table.columns[column_index].cells[starting_row:])
if is_containing_line(cell)]

print(cell._tc.xml) for cell that contains line shape:

Answer 1

There is no API support for this in python-docx.

However, this function will tell you whether a drawing (inline-shape) is present in a paragraph. Note that depending on the Word version, such an item may appear as a <w:pict> (bitmap image) element instead of a <w:drawing> (vector art) element:

def has_inline_shape(paragraph):
    """Return True if `paragraph` contains an inline shape."""
    return (
        bool(paragraph._p.xpath(".//w:drawing"))
        or bool(paragraph._p.xpath(".//w:pict"))
    )

You can apply it to each paragraph in a cell to determine whether the cell contains such a shape:

def cell_contains_inline_shape(cell):
    """Return True if an inline-shape appears in `cell`."""
    return any(
        has_inline_shape(paragraph)
        for paragraph in cell.paragraphs
    )
