Question

我想在网页上显示一些信息，以便用户根据需要向下钻取数字。我知道我想要它做什么，但不确定从哪里开始寻找它。

我想做的是以下（或类似的事情）

     Date     Item     Total
   + 7/2/2018 Apples   1000

单击+（或任何行，甚至是行）时，它会扩展为以下内容

   Date      Item              Total
 - 7/2/2018  Apples            1000
   7/2/2018  Honey Crisp       250
   7/2/2018  Golden Delicious  500
   7/2/2018  Granny Smith      250

像这样可能吗？我从哪里开始看？
