merge table from 2 csv files

[#1]

Hi,

I have two csv files (round1.csv & round2.csv). How can I merge into a new table mergeRound.csv. I was trying to play around with the 

Last Name,First Name,Number combine should be the same. The rest of the columns should be merge.

I was playing around the Tables menu but cannot figure it out before putting it to JSL.

Thanks.

I would set up your data in an analytical form.  Basically, the data are concatenated.  See illustration below:

Jim,

Last Name, First Name, and Number will be my unique key.

I was going to compare each individual assist, block, score, dunk, etc... via plot Last Name, First Name, and Number. by between round 1 & round 2. That's why I put it in the same row. 

Not sure if that is the right thing to do.

The format that I suggest is supported within Graph Builder to produce your suggested graph(s)

Below is a script that produces these graphs from the Concatenated form of the data.  Additionally, if your merged form of the data the

     Tables==>Split

can easily be used to split the data to a row based format
