Solution 1

The data that you are receiving is an object array. You can access them like this:
data[0].pkMenuId
data[0].Submenu
data[1].pkMenuId
... and so on.

In short:
[] = array and {} = object so [{}, {},...] is an object array. This example array is empty by the way.

JavaScript

$.ajax({async:true, dataType:"json", url:"page.aspx", type:"GET"}).done(function(res) { 
            for(i = 0; i < res.Table.length; i++) {
                tblHtml += '<table><tbody><tr class="rowwhitesmoke" dirid="+res.Table[i].data1+" id="trHand" onclick="fundata(this);">';
                tblHtml += '<td align="center">'+res.Table[i].data2+'</td>';
                tblHtml += '</tr></tbody></table>';
            }
            tblHtml += '';
            dvgrd.html(tblHtml);
        });
