Add and delete columns dynamically in an HTML table

To add new rows to a table (or table section) you can use insertRow, but there isn't an equivalent insertColumn in the  DOM table methods . So what you can do is iterate the rows in the table (or table section), and call insertCell for each row. Javascript:   tableaddcolumn.js // 2006-08-21 - Created // 2006-11-05 - Modified - head and body function addColumn(tblId) { var tblHeadObj = document.getElementById(tblId).tHead; for (var h=0; h<tblHeadObj.rows.length; h++) { var newTH = document.createElement('th'); tblHeadObj.rows[h].appendChild(newTH); newTH.innerHTML = '[th] row:' + h + ', cell: ' + (tblHeadObj.rows[h].cells.length - 1) } var tblBodyObj = document.getElementById(tblId).tBodies[0]; for (var i=0; i<tblBodyObj.rows.length; i++) { var newCell = tblBodyObj.rows[i].insertCell(-1); newCell.innerHTML = '[td] row:' + i + ', cell: ' + (tblBodyObj.rows[i].cells.length - 1) } } function deleteColumn(tblId) { v...
