在CSS中，我們可以通過設(shè)置表格的樣式來實現(xiàn)縱向滾動條的功能，以下是一些實現(xiàn)步驟：

1、我們需要創(chuàng)建一個表格，并指定其寬度和高度。

<table id="myTable" style="width: 100%; height: 200px;">
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr>
    <td>Some data</td>
    <td>Some data</td>
    <td>Some data</td>
  </tr>
  <tr style="height: 100px; overflow-y: auto;"> // 這里設(shè)置了一個高為100px的單元格，并開啟了縱向滾動條，如果內(nèi)容超出這個高度，就會顯示滾動條，這個單元格可以包含更多的數(shù)據(jù)。 <div style="height: 100px; overflow-y: auto;"> <p style="height: 200px; line-height: 20px; text-align: center;">This is some long text that will make the cell taller than the specified height of 100px, thus showing the scrollbar when the content is longer than the cell's height.</p></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div>
