Adding Rows and Columns to a table depending requirements

Question

Hi all,
I have created a table with one row and 2 columns of a table. My client requested adding form one to 3 columns of the right table and rows as well, depending business requirements.
I can add coding add columns on the right, but I cannot add rows because the columns dynamic.
I tried to write the coding for adding rows but it is not successful.  Please help.
event : click - add colum button
for (var i = 0; i < form1.page1.Table1._Row1.count; i++){
var newrow = form1.page1.Table1.resolveNode("Row1[" + i + "]");
var newrow2 = form1.page1.Table1.resolveNode("HeaderRow[" + i + "]");
newrow._Col3D.addInstance(0);
newrow2._Col3D.addInstance(0);
i also published my file for your reviewing.

When you are adding instances it uses the default properties of the object...
If its hidden as a default value in the form and you add an instance, the new instance will be hidden..
So if you have 3 columns in your default row and trying to add an instance withthe 5 columns it will only add a row with 3 columns..
If you want to add the columns to the table, you must add the column to each new row instance.
E.g.:
var intCount = xfa.resolveNode("page1.table1.Row1").instanceManager.count;
form1.page1.table1._Row1.addInstance(1);
xfa.resolveNode("page1.table1.Row1[" + intCount.toString() + "].Col3D").addInstance(1);
