JavaScript

// Obtain relevant interface elements
const bodySection = document.querySelectorAll("tbody")[0];
const row = bodySection.rows[0]; // Select the first row of the body section
const cells = row.cells; // The collection is live, therefore always up-to-date
const cellNumberDisplay = document.querySelectorAll("output")[0];

const addButton = document.getElementById("add");
const removeButton = document.getElementById("remove");

function updateCellNumber() {
  cellNumberDisplay.textContent = cells.length;
}

addButton.addEventListener("click", () => {
  // Add a new cell at the end of the first row
  const newCell = row.insertCell();
  newCell.textContent = `Cell ${cells.length}`;

  // Update the row counter
  updateCellNumber();
});

removeButton.addEventListener("click", () => {
  // Delete the row from the body
  row.deleteCell(-1);
