		//	caching using a static within the method is faster than a class static,
		//		though it's additional memory overhead
		static $_indexCache = array();
		if (!isset($_indexCache[$pColumnIndex])) {
			// Determine column string
			if ($pColumnIndex 
<p>将列的数字序号转成字母使用:</p>
<p>PHPExcel_Cell::stringFromColumnIndex($i); // 从o开始</p>
<p>将列的字母转成数字序号使用:</p>
<p>PHPExcel_Cell::columnIndexFromString(‘AA’);</p>
