uj5u.com熱心網友回復：

我已經創建了一個解決方案。檢查這是否適合您。我為表 td 創建了 max-width 并添加了 thead 和 tbody 以確保語意正確。

#customers {
  font-family: Arial, Helvetica, sans-serif;
  border-collapse: collapse;
  width: 100%;
}

#customers td,
#customers th {
  border: 1px solid #ddd;
  padding: 8px;
}

#customers tr:nth-child(even) {
  background-color: #f2f2f2;
  height: 20px;
  overflow: hidden;
}

#customers tr:hover {
  background-color: #ddd;
}

#customers th {
  padding-top: 12px;
  padding-bottom: 12px;
  text-align: left;
  background-color: #04aa6d;
  color: white;
}

tbody tr td {
  max-width: 100px;
}
tbody tr td div {
  height: 50px;
  overflow-y: scroll;
}
