Solve the following python programming problem given the following code:
def _write_cell_xfs(self, number_format_table, fonts_table, fills_table, borders_table) : 
    ' write styles combinations based on ids found in tables ' 
    cell_xfs = SubElement (self._root, 'cellXfs', { 
        'count' : ('%d' % (len (self._style_list) + 1)), 
}) 
    def _get_default_vals() : 
        return dict (numFmtId = '0', fontId = '0', fillId = '0', xfId = '0', borderId = '0') 
SubElement (cell_xfs, 'xf', _get_default_vals ()) 
    for st in self._style_list : 
        vals = _get_default_vals () 
        if (hash (st.font) != hash (style.DEFAULTS.font)) : 
            vals ['fontId'] = fonts_table [hash (st.font)] 
            vals ['applyFont'] = '1' 
if (hash (st.borders) != hash (style.DEFAULTS.borders)) : 
            vals ['borderId'] = borders_table [hash (st.borders)] 
            vals ['applyBorder'] = '1' 
if (hash (st.fill) != hash (style.DEFAULTS.fill)) : 
            vals ['fillId'] = fills_table [hash (st.fill)] 
            vals ['applyFillId'] = '1' 
if (st.number_format != style.DEFAULTS.number_format) : 
            vals ['numFmtId'] = ('%d' % number_format_table [st.number_format]) 
            vals ['applyNumberFormat'] = '1' 
if (hash (st.alignment) != hash (style.DEFAULTS.alignment)) : 
            vals ['applyAlignment'] = '1' 
node = SubElement (cell_xfs, 'xf', vals) 
        if (hash (fonts_table.alignment) != hash (style.DEFAULTS.alignment)) : 
            alignments = {

            for align_attr in ['horizontal', 'vertical'] : 
                if (hash (getattr (st.alignment, align_attr)) != hash (getattr (style.DEFAULTS.alignment, align_attr))) : 
                    alignments [align_attr] = getattr (st.alignment, align_attr) 
SubElement (node, 'alignment', alignments)
