我试图得到一个包含所有行和详细信息的表,但这些详细信息必须隐藏,直到我单击“父”行,这一切都正常,但我的详细信息表不适合整行的长度。

var expandirButton = document.getElementsByClassName("expandir");
for (var i = 0; i < expandirButton.length; i++) {
  expandirButton[i].addEventListener("click", function() {
    this.classList.toggle("active");
    var tablaAnidada = this.nextElementSibling;
    if (tablaAnidada.classList.contains("tabla-anidada")) {
      if (tablaAnidada.style.display === "block") {
        tablaAnidada.style.display = "none";
      } else {
        tablaAnidada.style.display = "block";
      }
    }
  });
}
table {
  border-collapse: collapse;
  width: 100%;
  border: 1px solid #ddd;
}

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

th {
  background-color: #4CAF50;
  color: white;
}

tr:nth-child(even) {
  background-color: #f2f2f2
}

/* Estilo para ocultar la tabla anidada */

.tabla-anidada {
  display: none;
}
<!DOCTYPE html>
<html>

<head>
  <meta charset="utf-8">
  <title>Tabla anidada</title>
</head>

<body>

  <h2>Tabla anidada</h2>

  <table id="myTable">
    <tr>
      <th>Nombre</th>
      <th>Apellido</th>
      <th>Edad</th>
    </tr>
    <tr class="expandir">
      <td>John</td>
      <td>Doe</td>
      <td>23</td>
    </tr>
    <tr class="expandir">
      <td>Mary</td>
      <td>Moe</td>
      <td>31</td>
    </tr>

    <!-- Fila que se expande -->
    <tr class="expandir">
      <td colspan="3">July</td>
    </tr>

    <!-- Nueva fila para la tabla anidada -->
    <tr class="expandir tabla-anidada">
      <!-- Agregue el atributo "colspan" a esta celda -->
      <td colspan="3">
        <table id="myNestedTable">
          <tr>
            <th>Ciudad</th>
            <th>Pais</th>
          </tr>
          <tr>
            <td>New York</td>
            <td>USA</td>
          </tr>
          <tr>
            <td>Paris</td>
            <td>Francia</td>
          </tr>
        </table>
      </td>
    </tr>
  </table>
</body>

它应该工作,因为我做了测试与前一行,七月,它的作品.实际上,如果我擦除.tabla-anidada类从css,它显示了它应该的方式,没有隐藏功能明显.似乎这一切都发生时,javascript被添加.我已经尝试创建不同的css类为每个表,addinng宽度样式属性在不同的地方,等等,等等.

表并不总是很好地处理非表显示类型。我将您的tablaAnidada.style.display = "block";更改为tablaAnidada.style.display = "table-row";,我认为这可能是您想要的结果。

var expandirButton = document.getElementsByClassName("expandir");
for (var i = 0; i < expandirButton.length; i++) {
  expandirButton[i].addEventListener("click", function() {
    this.classList.toggle("active");
    var tablaAnidada = this.nextElementSibling;
    if (tablaAnidada.classList.contains("tabla-anidada")) {
      if (tablaAnidada.style.display === "block") {
        tablaAnidada.style.display = "none";
      } else {
        tablaAnidada.style.display = "block";
      }
    }
  });
}
table {
  border-collapse: collapse;
  width: 100%;
  border: 1px solid #ddd;
}

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

th {
  background-color: #4CAF50;
  color: white;
}

tr:nth-child(even) {
  background-color: #f2f2f2
}

/* Estilo para ocultar la tabla anidada */

.tabla-anidada {
  display: none;
}
