表類無法在 html/css 中識別/讀取

Question

我有一個表，該表應該具有“table-class”類，但是該類甚至無法識別/讀取，並且屬性也不會顯示在表中。我正在使用 azure appServiceEditor，當我運行程式碼時，輸出只是一個預設樣式表，因此不會讀取 class="table-class" 的屬性。但是，當我插入任何其他類別而不是“表類”時，會顯示屬性。我不明白問題出在哪裡。

.table-class {
  position: absolute;
  display: block;
  font-family: arial, sans-serif;
  border-collapse: collapse;
  z-index: 10000000;
  background-color: rgba(0, 0, 0, 0.5);
  border-radius: 5%;
  color: white;
}

.table-class td,
th {
  border: 1px solid #dddddd;
  text-align: left;
  padding: 8px;
}

.table-class tr:nth-child(even) {
  background-color: rgba(0, 0, 0, 0.6);
}

<table class="table-class">
  <tr>
    <th>Company</th>
    <th>Contact</th>
    <th>Country</th>
  </tr>
  <tr>
    <td>Alfreds Futterkiste</td>
    <td>Maria Anders</td>
    <td>Germany</td>
  </tr>
  <tr>
    <td>Centro comercial Moctezuma</td>
    <td>Francisco Chang</td>
    <td>Mexico</td>
  </tr>
  <tr>
    <td>Ernst Handel</td>
    <td>Roland Mendel</td>
    <td>Austria</td>
  </tr>
  <tr>
    <td>Island Trading</td>
    <td>Helen Bennett</td>
    <td>UK</td>
  </tr>
  <tr>
    <td>Laughing Bacchus Winecellars</td>
    <td>Yoshi Tannamuri</td>
    <td>Canada</td>
  </tr>
  <tr>
    <td>Magazzini Alimentari Riuniti</td>
    <td>Giovanni Rovelli</td>
    <td>Italy</td>
  </tr>
</table>

Answer 1

.table {
  position: absolute;
  display: block;
  font-family: arial, sans-serif;
  border-collapse: collapse;
  z-index: 10000000;
  background-color: rgba(0, 0, 0, 0.5);
  border-radius: 5%;
  color: white;
}

.table td,
th {
  border: 1px solid #dddddd;
  text-align: left;
  padding: 8px;
}

.table tr:nth-child(even) {
  background-color: rgba(0, 0, 0, 0.6);
}

Company	Contact	Country
Alfreds Futterkiste	Maria Anders	Germany
Centro comercial Moctezuma	Francisco Chang	Mexico
Ernst Handel	Roland Mendel	Austria
Island Trading	Helen Bennett	UK
Laughing Bacchus Winecellars	Yoshi Tannamuri	Canada
Magazzini Alimentari Riuniti	Giovanni Rovelli	Italy

使用此程式碼而不是表類別
