If a site is using a layout table (that is, there are no header <th> elements and the information in the table does not need column or row headers to make sense), then add the attribute role=”presentation” to the <table> element.  

If a site is using a table as a data table - make sure it is using the proper markup (using header <th> elements where appropriate).  

Layout tables can be removed if they are in the footer (causing responsiveness issues).  Use the CSS class “grid-X” (where x is some number 1-12).  The full width of an element in a container is grid-12.  If there are two elements in a container and you’d like them to be equal width, use class=”grid-6” on each element.  See the instructions on adding CSS class names and HTML elements and attributes to the WYSIWYG if needed.
