If you can use Excel, there is a Query from Excel Files function:
- Define name for primary table - Table A (Formulas tab -> Define name)
- Define name for secondary table - Table B
- Go to Data tab, select "From Other Sources", and from the dropdown, select "From Microsoft Query"
- Select your CSV file and confirm that you want to merge the columns manually
- In the following window "Query from Excel Files", drag&drop the Name column of Table A into the Name column of Table B - a link between these columns will be created
- Go to File menu, click "Return Data to MS Office Excel", an Import Data dialog will pop up
- Select the sheet into which you would like the matched data to be imported
- Click OK - you should see matched data with columns from both tables
Or if you don't mind uploading your CSV files to an online service, you can use for example http://www.gridoc.com/join-tables and join the spreadsheets using drag&drop (Disclaimer: I am author of the tool).
Hope this helps.
