我創建了一個多重粘性頭:

.content {
  margin: 0px;
  text-align: center
}

.dataTable {
  margin: 0px;
  padding: 0px;
  width: 100%;
}

.dataTable thead {
  top: 36px;
}

.header {
  background: #ddd;
  color: #222;
  margin: 0px;
  position: sticky;
  padding: 0.5em;
  text-align: center;
}

#header01 {
  margin: 0px;
  top: 0;
}

.mainParent {
  background: rgba(222, 222, 222, 0.10);
  text-align: center;
}

.mainParent {
  margin: 0em
}

<div class="mainParent">

  <div id="content01" class="content">
