javascript loop through table rows and columns code example
Example 1: Javascript looping through table
var table = document.getElementById("myTable");
for (let i in table.rows) {
let row = table.rows[i]
//iterate through rows
//rows would be accessed using the "row" variable assigned in the for loop
for (let j in row.cells) {
let col = row.cells[j]
//iterate through columns
//columns would be accessed using the "col" variable assigned in the for loop
}
}

for (var i = 0, row; row = table.rows[i]; i++) {
//iterate trough columns
for (var j = 0, col; col = row.cells[j]; j++) {
// do something
}
