如何让TabControl使用其父级的全宽？

<div class="tab-control">
  <div class="tab-item">Tab 1</div>
  <div class="tab-item">Tab 2</div>
  <div class="tab-item">Tab 3</div>
</div>

.tab-control {
  display: flex;
  justify-content: space-between;
  width: 100%;
}

.tab-item {
  flex-grow: 1;
  text-align: center;
  padding: 10px;
  background-color: #eee;
  border: 1px solid #ccc;
}
