Table class cannot be recognized/read in html/css

Question

I have a table that is supposed to have a "table-class" class, but the class isn't even recognized/read and the properties don't show up in the table. I'm using azure appServiceEditor and when I run the code the output is just a default stylesheet so the attribute of class="table-class" is not read. However, when I insert any other class instead of "Table Class", the properties are displayed. I don't understand what the problem is.

.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>

.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);
}
