Describes whether any elements inside this element and the element itself may offer the expanded view. Tables can have an expanded view. Note that you should configure this on the outermost element of your table e.g. table element in CALS tables, table element in XHTML tables, table element in TEI tables and simpletable element in simple tables. This should be set to false for elements that are rendered as multiple columns, where block content can occur horizontally next to other content. Setting allowExpansionInContentView to true for elements that are rendered as multiple columns may introduce unexpected visual issues.
Default value is true.
