Hi all the dynamically created controls are available in Request.From Collection object.

You can access them in postback as

C#

for(int i=0;i<request.form.count;i++)>
{
  string value = Request.Form["txtDetails"+i].ToString();
}

In your case you can loop 2 times(to append row and column id in your case) to get all the textbox values you have created.

Before I have done in the following approach. but here the processing happens on server side..

1. I have created a webmethod in c#,which uses HTMLTable class and create a HTML Table(based on params), Textboxes have been added to the table Cell.
2. Converted above HTMLTable to Html Table markup and returned the html as text to the jquery ajax function.
3. on success i have placed the returned HTML in a div. On postback the all the controls were available in Request.Form object.

You can use this method, depending on your requirements.
