如图：之前一直用定位 现在发现可以用css写
background: linear-gradient(to top, #306eef, #306eef) left top no-repeat,
/*上左*/ linear-gradient(to right, #306eef, #386eef) left top no-repeat,
/*左上*/ linear-gradient(to left, #386eef, #306eef) right top no-repeat,
/*上右*/ linear-gradient(to bottom, #306eef, #306eef) right top no-repeat,
/*上右*/ linear-gradient(to left, #386eef, #386eef) left bottom no-repeat,
/* */ linear-gradient(to bottom, #386eef, #306eef) left bottom no-repeat,
/*左下*/ linear-gradient(to top, #396eef, #396eef) right bottom no-repeat,
/* 石*/ linear-gradient(to left, #306eef, #306eef) right bottom no-repeat; /*右下*/
background-size: 2px 16px, 16px 2px, 2px 16px, 16px 2px;
顺便记录一下给单数盒子变色
.table-body:nth-child(odd) {
background: rgba(97, 156, 249, 0.5);
}
最后再记录一下给某个盒子隐藏下滑条
.tableBody::-webkit-scrollbar {
width: 0;
}
