当一行中只有一个单元格被选中时,是否可以使用css和样式来改变html表格中整行的背景?

我希望能够区分用户在html表格中选择的单元格的行。
有没有办法用CSS和样式来实现这一点,或者我需要用JQuery和JavaScript来编程?
例如,用户可以点击第一行的BA单元格,然后我希望第一行的背景是浅蓝色。

$('.table-add').click(function() {

  $TABLE.find('table').append($clone);

  $(this).parents('tr').detach();

  $row.prev().before($row.get(0));

通过在样式中添加以下代码,使用has,选中的行将以不同的颜色显示,而不需要jquery或javascript代码。

tr:has(td:focus-visible) {
 background-color: aquamarine;
}

jquery实现了一个has选择器,您可以选择所有具有特定子属性父对象

$('td[contenteditable="true"]').click(function() {
  $( "tr" ).has('td[contenteditable="true"]').removeClass('selected');
  $( "tr" ).has('td[contenteditable="true"]:focus').addClass('selected');
});

用于选择具有焦点的TD的选择器是td[contenteditable="true"]:focus
x一个一个一个一个x一个一个二个一个x一个一个三个一个
