display:table-cell的padding是怎么确定的

Question

我正在尝试制作一个类似于 table 的布局，药物名称出现在左侧，数据占据 table 的其余部分。简单地说：

           +-------------+------------+
medicine 1 |  some data  | some data  |
           +-------------+------------+
medicine 2 |  some data  | some data  |
           +-------------+------------+

因为我想保持数据网格动态，所以我使用两个 <div> 样式的 display:table-cell 作为两个容器，左边一个用于所有药物名称，右边一个对于数据网格。这两个table-cell <div>里面有几个inner <div>，但是我不知道为什么我用的时候左边那个在顶部有一个大的padding area Chrome 检查界面以进行调查（请参见下图）：

我不太确定哪一部分出了问题，而且检查界面没有给我似乎相关的信息。我想学习如何处理这种情况。这是供您参考的 html 代码：

<div style="display:table">
  <div style="display:table-row">
    <div style="display:table-cell">
      <div style="height:85px; width:170px; text-align:right; font-size:13px; margin-right:5px">

这是关于垂直对齐的。默认设置为基线并生成此输出。只需在 table-cell 上将对齐方式更改为 top，您就不会遇到此问题：

<div style="display:table">
  <div style="display:table-row">
    <div style="display:table-cell;
    vertical-align: top;">
      <div style="height:85px; width:170px; text-align:right; font-size:13px; margin-right:5px">
        Dexedrine Spansules (Dextroamphetamine, ER) <br/><span style="font-style:italic">(20mg)</span>
      </div>
      <div style="height:85px; width:170px; text-align:right; font-size:13px; margin-right:5px">
        Methamphetamine (Desoxyn, IR) <br/><span style="font-style:italic">(15mg)</span>
      </div>
    </div>
    <div style="display:table-cell;
    vertical-align: top; overflow:hidden; max-width:800px">
      <div id="medicine_table_container_2" class="medicine-table-container" style="position:relative; left:0">
        <div style="white-space:nowrap; font-size:0px">
          <div style="display:inline-block; background-color:yellow; width:130px; height:85px; border:1px solid #999; font-size: 12px; white-space:normal">
            <div>
              <div style="display:inline-block; width:70px; height:45px">
                Morning<br/>-
              </div>
              <div style="display:inline-block; width:50px; height:45px">
                Noon<br/>5mg
              </div>
            </div>
            <div>
              <div style="display:inline-block; width:70px; height:35px">
                Afternoon<br/>12mg
              </div>
              <div style="display:inline-block; width:50px; height:35px">
                Evening<br/>-
              </div>
            </div>
          </div>
        </div>
        <div style="white-space:nowrap; font-size:0px">
          <div style="display:inline-block; background-color:yellow; width:130px; height:85px; border:1px solid #999; font-size: 12px; white-space:normal">
            <div>
              <div style="display:inline-block; width:70px; height:45px">
                Morning<br/>-
              </div>
              <div style="display:inline-block; width:50px; height:45px">
                Noon<br/>5mg
              </div>
            </div>
            <div>
              <div style="display:inline-block; width:70px; height:35px">
                Afternoon<br/>12mg
              </div>
              <div style="display:inline-block; width:50px; height:35px">
                Evening<br/>-
              </div>
            </div>
          </div>
        </div>
      </div>
    </div>
  </div>
</div>

由于您的代码有点复杂，这里有一个基本的代码可以重现问题并更好地理解正在发生的事情：

.table {
  display: table;
  border: 1px solid;
  margin: 5px;
}

.table>div {
  display: table-row;
}

.table>div>span {
  display: table-cell;
  padding: 0 5px;
}

.table>div>span span {
  display: inline-block;
}

baseline
<div class="table">
  <div>
    <span>one line</span>
    <span><span>two <br> line (inline-block)</span></span>
  </div>
</div>
baseline
<div class="table">
  <div>
    <span>two<br> line</span>
    <span><span>two <br> line (inline-block)</span></span>
  </div>
</div>
baseline (with overflow:hidden)
<div class="table">
  <div>
    <span>one line</span>
    <span><span style="overflow:hidden;">two <br> line</span></span>
  </div>
</div>
baseline (with overflow:hidden)
<div class="table">
  <div>
    <span>one line</span>
    <span><span style="overflow:hidden;">another line</span></span>
  </div>
</div>
top will fix all the cases
<div class="table">
  <div>
    <span style="vertical-align:top;">one line</span>
    <span><span>two <br> line</span></span>
  </div>
</div>
<div class="table">
  <div>
    <span style="vertical-align:top;">one line</span>
    <span><span style="overflow:hidden;">two <br> line</span></span>
  </div>
</div>
<div class="table">
  <div>
    <span style="vertical-align:top;">one line</span>
    <span><span style="overflow:hidden;">another line</span></span>
  </div>
</div>
<div class="table">
  <div>
    <span style="vertical-align:top;">two<br> line</span>
    <span><span>two <br> line (inline-block)</span></span>
  </div>
</div>

您可以清楚地看到 inline-block（和 overflow:hidden）的使用是这里的罪魁祸首，因为它使基线计数器的计算变得直观和意外。

我看到 Temani Afif 已经为您的原始问题提供了。但是，如果无论如何它对您或其他任何人都有帮助，这里是 table 和 sub-tables

的基本结构

样式

<style>
    .table {
        display:table; border:1px solid #ccc; border-collapse:collapse
    }
    .table .row {
        display:table-row; border:1px solid #ccc; border-collapse:collapse
    }
    .table .row .headercell {
        display:table-cell; border:1px solid #ccc; height: 80px; width: 150px; border-collapse:collapse
    }
    .table .row .cell {
        display:table-cell; border:1px solid #ccc; height: 80px; Width: 300px; border-collapse:collapse
    }
</style>

Table结构

<div class="table">
    <div class="row">
        <div class="headercell">
            Row1
        </div>
        <div class="cell">
            <div class="table">

                        Cell1
                    </div>
                    <div class="cell">
                        Cell2
                    </div>
                </div>
                <div class="row">
                    <div class="cell">
                        Cell3
                    </div>
                    <div class="cell">
                        Cell4
                    </div>
                </div>
            </div>
        </div>
    </div>
    <div class="row">
        <div class="headercell">

        </div>
        <div class="cell">
            <div class="table">
                <div class="row">
                    <div class="cell">
                        Cell1

                    <div class="cell">

                </div>
            </div>
        </div>
    </div>
</div>
