I need to club data in a data table into a single row based on a condition

For example

In this table i have different rows but the last three rows have the same date. I need to have the data in the table to be combined by date

ie in the rows having same date the data in the other columns have to be added like the image below

My datatable contains very huge amounts of data so can you help in solving this in less no of iterations??
