将表列表按列名分​​组（包括示例）

Question

i have a table that i need to group into divs

rated | rater | team | score | subject
john    mike     TA     10      math
john    mike     TA     10      PE
john    jane     TA     9       math
john    jane     TA     9       PE
kim     lee      TB     5       math
kim     min      TB     2       math

i need it to look like

 TA
    john
     RATER    MATH  PE         
     mike      10   10
     jane      9     9
 TB
   kim
    RATER     MATH  PE
    lee        5
    min        2

In my view I'm just iterating these values from a LINQ with a

@foreach (var item in Model) 

Any help would be appreciated.

It looks like you want to transpose the columns and rows.

Check out this method from this blog: http://higherlogics.blogspot.com/2010/05/linq-transpose-extension-method.html

Here's the code sample:

public static IEnumerable<IEnumerable<T>> Transpose<T>(
     this IEnumerable<IEnumerable<T>> source)
{
return from row in source
       from col in row.Select(
           (x, i) => new KeyValuePair<int, T>(i, x))
       group col.Value by col.Key into c
       select c as IEnumerable<T>;
}
