I have a datatable like below:

Name        Address
Name1       Address1
Name2       Address2
Name3       Address1
Name4       Address3
Name5       Address2
Name6       Address4

I want the above table like:

Name        Address
Name1       Address1
Name3       
Name2       Address2
Name5       
Name4       Address3
Name6       Address4

What I have tried:

I have tried like this:

dt = dt.AsEnumerable().OrderBy(r => r.Field<string>("Craft")).CopyToDataTable();

but it's only getting this below table:

Name        Address
Name1       Address1
Name3       Address1
Name2       Address2
Name5       Address2
Name4       Address3
Name6       Address4

and then sort Names (according to Address)

and the Address value should display in middle(only once) adjacent to names (under address column only)

remove the duplicate values in Address column Like:

Name      Address
Name1       Address1
Name3       
Name2       Address2
Name5

this is what i want

That's not a Group: grouping condenses information into summaries, not collects them together. This may help you understand the idea - it's for SQL queries, but its; exactly the same principle: SQL GROUP By and the "Column 'name' is invalid in the select list because..." error[^]

What you are trying to do is sort the records, not group them, for which you want OrderBy:

dt = dt.AsEnumerable().OrderBy(r => r.Field<string>("Address")).CopyToDataTable();
