autofit is broken

Hi, the autofit method is broken in 0.8.5. Tables behave like if the columns have fixed width. When autofit is set, tag(s) <w:tcW/> for the table(s) in document.xml should be set to something like <w:tcW w:type="auto" w:w="0"/> and not <w:tcW w:type="dxa" w:w="13606"/> (for example)

Here is a snippet to the autofit works. It load every tables and set tblW and cells width to type auto.

Any idea how to implement it to the library core library? Adding a tblW children to tblPr and update the autofit setter?

def set_autofit(doc: Document) -> Document:
    """
    Hotfix for autofit.
    """
    for t_idx, table in enumerate(doc.tables):
        doc.tables[t_idx].autofit = True
        doc.tables[t_idx].allow_autofit = True
        doc.tables[t_idx]._tblPr.xpath("./w:tblW")[0].attrib["{http://schemas.openxmlformats.org/wordprocessingml/2006/main}type"] = "auto"
        for row_idx, r_val in enumerate(doc.tables[t_idx].rows):
            for cell_idx, c_val in enumerate(doc.tables[t_idx].rows[row_idx].cells):
                doc.tables[t_idx].rows[row_idx].cells[cell_idx]._tc.tcPr.tcW.type = 'auto'
                doc.tables[t_idx].rows[row_idx].cells[cell_idx]._tc.tcPr.tcW.w = 0
    return doc

The cells in a column can be set to have w:type="auto" using this code:

for cell in column.cells:
    tc = cell._tc
    tcPr = tc.get_or_add_tcPr()
    tcW = tcPr.get_or_add_tcW()
    tcW.type = 'auto'

If you’re willing to depend on the w:tcPr and w:tcW elements already being there, it can be shortened to:

for cell in column.cells:
    cell._tc.tcPr.tcW.type = 'auto'

If someone has a proposal for when that should be done automatically, I’m willing to consider it, just clearly state the behavior you propose.
