[7.5] Failure/Error: parser on editor incorrectly parses custom table properties

[askonev]

I was gathering files with a script for builder and found this scenario

The set shade property (correctly displayed in the document) is not an attribute of the ooxml-parser object

docx.elements[1].properties.table_style.table_style_properties_list
                 .first.table_cell_properties.shade

result

     Failure/Error:
       expect(docx.elements[1].properties.table_style.table_style_properties_list
                  .first.table_cell_properties.shade.color.upcase)
     
     NoMethodError:
       undefined method `color' for nil:NilClass

Looked inside the documents and found that the style id set for the first cell

	<tblStyle w:val="1_634" />

Accordingly, in the styles.xml file we find out that in version 7.5 the supported properties have been significantly extended, but
table column property is written correctly

	<tcPr>
		<shd w:val="clear" w:color="ff0000" w:fill="ff0000" />
		<tcBorders>
		</tcBorders>
	</tcPr>

Here are two files compiled by one script on different versions of the editor for comparison purposes

table_pr_7.4.1.zip
table_pr_7.5.zip
