To traverse an HTML table with JavaScript and DOM Interfaces, we can use the following steps:

1. Get a reference to the table element using document.getElementById, document.querySelector, or any other appropriate method.
2. Access the rows property of the table element to get a collection of all the rows in the table.
3. Iterate over the rows using a loop or the forEach method.
4. Within each row, access the cells property to get a collection of all the cells in that row.
5. Iterate over the cells using a loop or the forEach method.
6. Perform any desired operations on each cell, such as accessing its content or modifying its attributes.

Here is an example code snippet that demonstrates how to traverse an HTML table using JavaScript and DOM Interfaces:

// Get a reference to the table element
const table = document.getElementById("myTable");

// Iterate over the rows
for (let i = 0; i < table.rows.length; i++) {
  const row = table.rows[i];

  // Iterate over the cells in the current row
  for (let j = 0; j < row.cells.length; j++) {
    const cell = row.cells[j];

    // Perform operations on each cell
    console.log(cell.textContent);
    // Modify cell attributes, e.g…
