C# - How To Create A Pivot Table With Dynamic Column Using Linq Tree Expression

i'm writing an asp.net C# web application; i have an in-memory datatable named 'table1' having three columns 'country', 'productId' and 'productQuantity'; i want to pivot that table in order to obtain a new table (suppose 'table2') having the first column 'country' as a fixed column and a dynamic number and names of columns 'product_1', 'product_2', ..., 'product_n' according to the total number of products existing in 'table1'; the first column 'country' must contain the country name; the dynamic generated columns 'product_1', 'product_2', ..., 'product_n' must contain the productQuantity that has been selled for each specific product in the specified country

i'm using Linq query expressions to write the code; the problem is that i cannot hard-code the names neither the values of the products; i cannot predict how much products exist in the datatable;

for now, i'm testing the results using the following expression :

[Code].....

i'm giving an example on how 'table1' looks like and how 'table2' must look like :
