为什么这两个相同的表根据浏览器宽度表现不同？

Question

我有这两个相同的表，但是当浏览器宽度改变时它们的行为有所不同。

看起来像一个溢出而另一个收缩以适应浏览器的宽度。但为什么会这样呢？

<div id="article-body">
  <br>
  <table style="border-collapse:collapse;" cellspacing="5" cellpadding="5" bordercolor="#ccc" border="1" align="center">
      <thead>
          <tr>
              <th scope="col">One Tow Three</th>
              <th scope="col">Two Four One</th>
              <th scope="col">Three to The One Two</th>
              <th scope="col">Fiour Something Hljfal lkdsjfals ladskjfalsd  dlkafjsdl asdlkfj ere</th>
          </tr>
      </thead>
      <tbody>
          <tr>
              <td>one cool drive</td>

              <td>six</td>
              <td>seven</td>
              <td>eight</td>
          </tr>

正如您在bin中看到的那样，没有附加CSS，它们仍然表现不同。但为什么？

一直在追逐这个bug几天，所以任何帮助将不胜感激。

Answer 1

你的桌子完全不相同。内容不同。不同数量的列。

如果您希望它们具有相同的宽度，则需要设置表格宽度。

table {
  width: 100%;
}

  <div id="article-body">
    <br>
    <table style="border-collapse:collapse;" cellspacing="5" cellpadding="5" bordercolor="#ccc" border="1" align="center">
        <thead>
            <tr>
                <th scope="col">One Tow Three</th>
                <th scope="col">Two Four One</th>
                <th scope="col">Three to The One Two</th>
                <th scope="col">Fiour Something Hljfal lkdsjfals ladskjfalsd  dlkafjsdl asdlkfj ere</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td>one cool drive</td>
                <td>overdrive pedals everywhwere<br>
                </td>
                <td>three</td>
                <td>four</td>
            </tr>
            <tr>

Answer 2

我假设这是因为你的专栏。最后一个表中有一列额外的内容。

编辑：这是因为th标签被其中的内容拉伸。宽度随着内容的宽度而拉伸。
