Group by variable and finding total numbers

Hi, I am beginner with KNIME,

I am trying to group data for column1 with other column values and need to arrive at number of grouped values. For example

Hotels C1 and Cancellation C2

Citadel, 0

Sherton, 1

Citadel, 1

Sherton, 0

Citadel, 0

Sherton, 0

Group by should result in

Citadel, 0, 2No

Sherton, 0, 2 No

Citadel, 1, 1No

Sheton, 1, 1No

How to achieve this in KNIME

Thanks
