Adding additional Columns to existing pivot table

Dear All,

I have created a pivot table with certain columns and converted to tabular format view and removed the subtotals.

Now, i want to add additional column "Date" which is not present in source of pivot table, adjacent to tabular format view. After adding the new column, how do i construct the relationship between newly added column and pivot table columns. Could you please let me know how to achieve this.

Thank You in Advance
