in a multi-row table, the mouse is required to display the shadow in the current row, and the shadow is projected down (box-shadow:-sharpdedcdc 1px 1px 2px;)
but because of the tight relationship between tr and tr, the projection below can only be seen when the mouse is over the last line of tr. In other cases, the projection of the side cannot be displayed normally
. Is there any way to make some space between the two tr elements to facilitate the display of shadows?
