Why does MS docx with tables open with blanks

I was sent a docx document that consists mainly of tables of text that correctly opens in MS Word 2007 and 2010. When opening it in LibreOffice 5.2.2 all the tables are blank (not even lines round them). AbiWord makes a fair stab at opening the document, and shows the tables - not necessarily formatted absolutely correctly - but the document is readable. This looks like a real bug in LibreOffice that needs fixing.
