Due to WordPress/WordPress@4c0c7fd, WP 4.3 now expects
$this->_column_headers
property in the list table object to have 4 entries. This commit fixes the offset notice that otherwise appears.In WP 4.2, the
list()
call insidesingle_row_columns()
simply drops the extra values, so this is backwards compatible.
