/*
 说明：
 		$(function() {
 			_tableColorDecorator.initTableColor(tblIdArr, colorArr, captionRowspan, enableClickEvent, clickCount, clickColor);
 		});

 		tblIdArr: 要加色的table的id数组["table_id1", "table_id2"]
		colorArr: 颜色数组[]，依次是：表头颜色，偶数行，奇数行，mouseover，传""将使用默认颜色
 		captionRowspan：表头的行数,
 		enableClickEvent: 是否开启点击事件, 默认关闭 
 		clickCount：传 1/2/"", 单击，双击，不启用
 		clickColor：颜色值，“”时候用默认颜色
