已解决
JS 如下
setInterval(function() {
//隐藏报表块report0的滚动条(此报表块名为report0,根据具体情况修改)
$("div[widgetname=report0]").find(".frozen-north").css({
'overflow-x': 'hidden',
'overflow-y': 'hidden'
});
$("div[widgetname=report0]").find(".frozen-center").css({
'overflow-x': 'hidden',
'overflow-y': 'hidden'
});
}, 1000);
