Combine row into a row

[gio1082]

Hi, 
I have a similar table as the table below where I have an id column and a Task column. Each ID can have multiple pending tasks.

ID Task

1  Copy

1  Paste

2  Copy

3  Erase

1 Erase

I want to combine the task in one column in power query. Like the table below. How can I do this 

ID Task

1  Copy, Paste, Erase

2  Copy

3  Erase

Thank you in advance!

group by ID, and concatenate the task value

=Table.Group(PreviousStepName,"ID",{"Task",each Text.Combine([Task],",")})
