当表格中存在水平滚动条时显示向右滚动箭头

.table-container {
  overflow-x: auto; /* 设置水平滚动条 */
  position: relative;
}

.table-container::after {
  content: "";
  position: absolute;
  top: 50%;
  right: 0;
  transform: translateY(-50%);
  width: 20px;
  height: 20px;
  background-image: url('right-arrow.png'); /* 替换为实际的箭头图标路径 */
  background-size: cover;
  background-repeat: no-repeat;
  opacity: 0.5; /* 设置箭头透明度 */
  pointer-events: none; /* 防止箭头遮挡表格内容的交互 */
}

.table-container:hover::after {
  opacity: 1; /* 鼠标悬停时显示完整的箭头 */
}
