Beginner Help with Power Query Merging

[Nicmills1]

Good morning everyone, 

Apologies in advance if this has been answered elsewhere, I've tried to look through previous threads and figure this out myself but to no avail. I am looking to try and merge the following:

My aim is to align matching values whilst maintaining each column in ascending order. Where there is no match on either data set a blank/null cell is inserted. As shown below:

I've tried a 'Full Outer Join Kind' but it just throws out a load of duplicates. 

Many thanks in advance

Hi,

Add index on each table with Table.Group and Join

= Table.Join(
    Table.Combine(
       Table.Group(
           Table1,
           {"Value 1"},
           {{"Data", each Table.AddIndexColumn(_,"Index 1")}})
       [Data]),
   {"Value 1", "Index 1"},
   Table.Combine(
       Table.Group(
           Source2,
           {"Value 2"},
           {{"Data", each Table.AddIndexColumn(_,"Index 2")}})
       [Data]),
   {"Value 2", "Index 2"},
   JoinKind.FullOuter
)
