use LINQ to map the date in table view on ASP.NET MVC3

[zeng6012]

so I have problem to map the date together in my ASP.NET APPLICATION.



as the image above that for instance I want to put the 9/4/2012 under 9/4/2012 and so on.

but I think my LINQ is wrong and I cant figure out, any advice please/

this one is for table header

@foreach (var date in person.OrderBy(x => x.Date).GroupBy(task => task.Date, entry => entry))
                {  
                    <th>
                        @date.Key
                    </th>
                }
                <th>
                    Total
                </th>

and I have for the column

@foreach (var date in task.GroupBy(hour => hour.Date, entry => entry))
                {
                    <td>
                        @date.Key
                    </td>
                }

After I map the date into the right position,I will start map the hour to the date the toal header is to calculate the sum of the week for that particular row. any suggest will be very thankful
