Hi @Amardeep100115 ，

You can use M-code such as below:

= Table.RemoveColumns(Source,{"test"}&{"test 2"})

{"test"}{"test 2"} are the tables I removed,and you will see that in my previous table there are 3 columns:Date ,test, test 2,and with the M-code,there are only 1 column left.

 
Best Regards,

You gave the video that answers your question?

Anyway, "Remove other columns" in Power query generates "M-code" for you (that is the whole point of the Query Editor, it generates the M code for you rather then having to create it yourself). You can also type in the M code yourself, I believe it is Table.SelectColumns() that returns a table with only the desired columns. 

Kind regards

This question is too broad to answer. Why can't you use the "remove columns" option in power query editor? What have you tried already? Where exactly are you getting stuck?
