Insert a row
var oTr = document.getElementById ("MyTable"). InsertRow (2);
var atext = new Array();
atext[0] = document.createTextNode ("contents of cell1");
atext[1] = document.createTextNode ("contents of cell2");
atext[2] = document.createTextNode ("contents of Cell3");
atext[3] = document.createTextNode ("contents of Cell4");
atext[4] = document.createTextNode ("contents of cell5");
for (var i=0; i<atext.length;i++) {
var oTd = Otr.insertcell (i);
Otd.appendchild (Atext[i]);
}
}
</script>

B modifying cell contents with DOM

<script language= "JavaScript" >
window.onload=function() {
var otable = document.getElementById ("MyTable");
Modify cell contents
otable.rows[3].cells[4].innerhtml = "content changed";
}
</script>

C Delete a cell or row using the DOM

var otable = document.getElementById ("MyTable");
Delete a row, followed by the line number is automatically padded
Otable.deleterow (2);
Delete a cell, and the back is automatically padded
otable.rows[2].deletecell (1);

this. ParentNode.parentNode.parentNode.removeChild (this. parentnode.parentnode);
}
window.onload=function() {
var otable = document.getElementById ("MyTable");
var oTd;
Add a Delete link dynamically
for (var i=1; i<otable.rows.length;i++) {
OTd = Otable.rows[i].insertcell (5);
otd.innerhtml = "<a href= ' # ' >delete</a>";
OTd.firstChild.onclick = Mydelete; Add Delete Event
}
}
</script>

E dynamically delete a column using the DOM

<script language= "JavaScript";
function  deletecolumn (otable,inum) {
    //Custom Delete Column function, That is, each row deletes the corresponding cell
     for ( var  i= 0 ; i<otable.rows.length;i++)
        otable . Rows[i].deletecell (iNum);
}
 
window.onload= function () {
