我有一张大桌.screens，里面有几张小桌子。较小的表具有数据，但是这些数据中的一些应该是可选的以显示。当用户单击复选框“附加数据”时，数据应该消失，但在此之后，应调整表的大小以保持红色边界元素的纵横比（这非常重要）。我计算新的尺寸并将其设置为表格，但由于某种原因，尽管设置了新的高度，但在浏览器调试中可以看到，实际尺寸不会受到影响。有什么问题？如何更改.screensRow的大小，就像有关其他数据的行被删除一样？这是小提琴：

$('#toggleData').change(function() {
if(this.checked) {
}
else {
var oldRowHeight = $('.screensRow:first-child').height();
var minusHeight = $('.screenContainer:first-child .channelInfo').height()+$('.screenContainer:first-child .channelInfoValues').height();
var newRowHeight = oldRowHeight-minusHeight;
$('.channelInfo').remove();
$('.channelInfoValues').remove();
var rows = $('.screensRow').length;
$('.screens').css({'height': rows*newRowHeight+'px'});
$('.screensRow').css({'height': newRowHeight+'px'});
}
});html {
