SharePoint2010 info path form with Add and Update operations on normal table.

Hi friends,

We are going to implement approval flow in that we used one SharePint list(Request List) and

attach document to Request list,

We implement sharepoint list browser based infopath form, But we are facing one issue in one of the scenerio,

Every time new Approval request is raised by employee as shown in below figure

Note:- Multiple Employee can upload single document for approval.The details of multiple employee in red Boarderd table. (One to many relationship)…..Single employee from the requester group  will submit the request.

(Below image is  our asp.net portal we are going to convert it in sharepoint)

As shown in the Image there are 2 things I have to do

1.       After click on Add/Update new row will get add in the table which one is red bordered.
2.       At time of edit item same view with requester details will be populate respect to request id

So please suggest me how to implement it in SharePoint2010 InfoPath form.

 We use InfoPath form for Request list and at time of submission Employee details save inRequestEmployee List with respect to their ReqID.

*I don’t have Repeating section due to browser based form.

I am using Below data structure for implement in that M using two lists one RequestList and another RequestEmployee list

so please suggest me how to implement it in SharePoint With InfoPath form or suggest me different trick for overall scenario.
