已找到解决办法，在body区加入以下代码就可以了。

<script type="text/javascript">
window.onload = function() {
    SyntaxHighlighter.highlight();
    setTimeout(function() {
        for (var i = 0,
        di; di = SyntaxHighlighter.highlightContainers[i++];) {
            var tds = di.getElementsByTagName("td");
            for (var j = 0,
            li, ri; li = tds[0].childNodes[j]; j++) {
                ri = tds[1].firstChild.childNodes[j];
                ri.style.height = li.style.height = ri.offsetHeight + "px";
            }
        }
    },
    100)
}
</script>
