css表头制作

CSS表头制作方法

固定表头（滚动时保持可见）

.table-container {
  height: 300px;
  overflow-y: auto;
}

table {
  width: 100%;
  border-collapse: collapse;
}

thead {
  position: sticky;
  top: 0;
  background-color: #f8f9fa;
}

基础样式设计

thead th {
  padding: 12px 15px;
  text-align: left;
  background-color: #3498db;
  color: white;
  font-weight: bold;
  border-bottom: 2px solid #2980b9;
}

悬停效果

thead th:hover {
  background-color: #2980b9;
  cursor: pointer;
}

斑马条纹表格

tbody tr:nth-child(odd) {
  background-color: #f2f2f2;
}

thead th {
  background-color: #4CAF50;
  color: white;
}

响应式表头

@media screen and (max-width: 600px) {
  thead {
    display: none;
  }

  td::before {
    content: attr(data-label);
    font-weight: bold;
    display: inline-block;
    width: 120px;
  }
}

带排序箭头的表头

th.sortable {
  position: relative;
  padding-right: 25px;
}

th.sortable::after {
  content: "↑↓";
  position: absolute;
  right: 8px;
  opacity: 0.5;
}

th.sort-asc::after {
  content: "↑";
  opacity: 1;
}

th.sort-desc::after {
  content: "↓";
  opacity: 1;
}

圆角表头

table {
  border-radius: 10px;
  overflow: hidden;
}

thead th:first-child {
  border-top-left-radius: 10px;
}

thead th:last-child {
  border-top-right-radius: 10px;
}
