Iterating Through HTML Table Rows and Cells in JavaScript

Iterating through table rows and cells in HTML using JavaScript allows you to access and manipulate the content of a table dynamically. Here are the steps to achieve this:

To iterate through table rows and retrieve cell values, use the following approach:

var table = document.getElementById("mytab1");
for (var i = 0, row; row = table.rows[i]; i++) {
   // Access each row using "row"
   for (var j = 0, col; col = row.cells[j]; j++) {
     // Access each column using "col"
   }  
}

This method lets you access both the table row and cell within each loop iteration.

If you only need to iterate through the cells, regardless of the row, use this code:

var table = document.getElementById("mytab1");
for (var i = 0, cell; cell = table.cells[i]; i++) {
     // Access each cell using "cell"
}

This approach iterates directly over the cells in the table.
