html - 使表比容器宽

Question

我有一张放在容器内的 table 。

我希望表格的两边都比容器宽 20px，但我无法让它工作。

我尝试将表格元素上的 margin: 0 auto; 更改为 margin: 0 -40px; 以便它在容器的每一侧悬垂 20px，但这只会将整个表格向左移动。

.container {
  width: 400px;
  display: block;
  border: 2px solid red;
  margin: 0 auto;
}

table {
  border-spacing: 1;
  border-collapse: collapse;
  background: white;
  border-radius: 10px;
  overflow: hidden;
  width: 100%;
  margin: 0 auto;
  position: relative;
}

table * {
  position: relative;
}

table td,
table th {
  padding-left: 8px;
}

table thead tr {
  height: 60px;
  background: #36304a;
}

table tbody tr {
  height: 50px;
}

table tbody tr:last-child {
  border: 0;
}

table td,
table th {
  text-align: left;
}

table td.l,
table th.l {
  text-align: right;
}

table td.c,
table th.c {
  text-align: center;
}

table td.r,
table th.r {
  text-align: center;
}

.header th {
  font-size: 18px;
  color: #fff;
  line-height: 1.2;
  font-weight: unset;
}

tbody tr:nth-child(even) {
  background-color: #f5f5f5;
}

tbody tr {
  font-size: 15px;
  color: #808080;
  line-height: 1.2;
  font-weight: unset;
}

tbody tr:hover {
  color: #555555;
  background-color: #f5f5f5;
  cursor: pointer;
}

.column {
  width: 160px;
}

.column:first-child {
  padding-left: 40px;
}

.column:last-child {
  padding-right: 40px;
}

<div class="container">
  <table>
    <thead>
      <tr class="header">
        <th class="column">1</th>
        <th class="column">2</th>
        <th class="column">3</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td class="column">mnbvbmvn</td>
        <td class="column" data-title="Points">28761528</td>
        <td class="column" data-title="Points">Some text here</td>
      </tr>
      <tr>
        <td class="column">adsfasdf</td>
        <td class="column" data-title="Points">12341234</td>
        <td class="column" data-title="Points">blah blah blah</td>
      </tr>
      <tr>
        <td class="column">ajgsgdsdjha</td>
        <td class="column" data-title="Points">85765</td>
        <td class="column" data-title="Points">some other text</td>
      </tr>
    </tbody>
  </table>
</div>

您可以设置最小宽度 min-width: 100%; 而不是 width 并根据需要设置负边距，以使表格水平居中。

.container {
  width: 400px;
  display: block;
  border: 2px solid red;
  margin: 0 auto;
}

table {
  border-spacing: 1;
  border-collapse: collapse;
  background: white;
  border-radius: 10px;
  overflow: hidden;
  min-width: 100%;
  position: relative;
  margin: 0 -20px;
}

table * {
  position: relative;
}

table td,
table th {
  padding-left: 8px;
}

table thead tr {
  height: 60px;
  background: #36304a;
}

table tbody tr {
  height: 50px;
}

table tbody tr:last-child {
  border: 0;
}

table td,
table th {
  text-align: left;
}

table td.l,
table th.l {
  text-align: right;
}

table td.c,
table th.c {
  text-align: center;
}

table td.r,
table th.r {
  text-align: center;
}

.header th {
  font-size: 18px;
  color: #fff;
  line-height: 1.2;
  font-weight: unset;
}

tbody tr:nth-child(even) {
  background-color: #f5f5f5;
}

tbody tr {
  font-size: 15px;
  color: #808080;
  line-height: 1.2;
  font-weight: unset;
}

tbody tr:hover {
  color: #555555;
  background-color: #f5f5f5;
  cursor: pointer;
}

.column {
  width: 160px;
}

.column:first-child {
  padding-left: 40px;
}

.column:last-child {
  padding-right: 40px;
}

<div class="container">
  <table>
    <thead>
      <tr class="header">
        <th class="column">1</th>
        <th class="column">2</th>
        <th class="column">3</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td class="column">mnbvbmvn</td>
        <td class="column" data-title="Points">28761528</td>
        <td class="column" data-title="Points">Some text here</td>
      </tr>
      <tr>
        <td class="column">adsfasdf</td>
        <td class="column" data-title="Points">12341234</td>
        <td class="column" data-title="Points">blah blah blah</td>
      </tr>
      <tr>
        <td class="column">ajgsgdsdjha</td>
        <td class="column" data-title="Points">85765</td>
        <td class="column" data-title="Points">some other text</td>
      </tr>
    </tbody>
  </table>
</div>
