title: Trapezoid table in HTML and CSS
body: <p>I'd like to make an IPA vowel diagram like this one:</p>
  
  <p><a href="https://i.stack.imgur.com/kmc9O.gif" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/kmc9O.gif" alt="enter image description here"></a></p>
  
  <p>I have made a table with 7 rows and 5 columns in HTML, but how do I <strong>change the shape of the table to trapezoid</strong> using CSS?</p>
  
  <p>I know that it's possible to draw a trapezoid in a graphics editor and then use the resulting image as a background in HTML, but I'd like to do do this with pure CSS if possible.</p>
