Change CKEditor Table Properties default width

If you want to make your CKEditor table responsive you need to set the table width in percentage rather then a fixed px or em value. By default, the table width value is set to 500 px. To change this value you need to add the following code in config.xml file.

CKEDITOR.on('dialogDefinition', function( ev ) {
	  var diagName =;
	  var diagDefn =;

	  if(diagName === 'table') {
	    var infoTab = diagDefn.getContents('info');
	    var width = infoTab.get('txtWidth');
	    width['default'] = "100%";

The above code will set the Table's default width to 100% instead of 500 as previously set.
