根据用户输入显示表格 n 次，然后具有根据单击的行显示/隐藏表格的功能

Question

我希望一个表格（table1）根据用户在输入表单中输入的数字显示 n 次。然后对于该表的每个实例，用户应该能够单击每一行，并且应该显示另一个相关的表。

到目前为止，我可以根据用户输入生成 table1 n 次。但是函数 myFunction_disease 仅适用于 table1 的第一次迭代。我希望 table1 的每个副本都能根据用户点击的内容独立控制。

这就是你需要的。要添加更多按钮和表格，您只需添加一个新的table 并提供一个新类table$（其中$ 是数字，例如：table4）并添加一个具有data-table-show=$ 属性的新按钮。就是这样?。

// Creating conditions
const numInput = document.getElementById('num'),
  conditionForm = document.getElementById('condition-form'),
  tablesContainer = document.getElementById('tables'),
  conditionText = tablesContainer.innerHTML;

conditionForm.onsubmit = async function(e) {
  e.preventDefault();
  const numValue = Number(numInput.value);

  await (tablesContainer.innerHTML += conditionText.repeat(numValue));

  addEventListenersToButtons();
}

// Working with table filtering
function addEventListenersToButtons() {
  let buttons = document.querySelectorAll('#tables tr.btn');

  buttons.forEach(function(button, i) {
    button.onclick = function() {
      const tables = button.parentNode.parentNode.parentNode.querySelectorAll('.data-table');

      tables.forEach(table => {
        if (table.classList.contains(`table${button.dataset.tableShow}`)) {
          table.classList.remove('hide')
        } else {
          table.classList.add('hide')
        }
      });

    }
  })
}

addEventListenersToButtons();

.tables-group table {
