Question

How to merge rows based on some ID field?

Original Table                   New Table

ID   | Field1 | Field2       ID     | Field1 | Field2
-----|------- |------         


        

Answer 1

In the ID column use the menu option: Edit Cells -> Blank down This should leave you with a table looking like:

ID   | Field1 | Field2 
-----|------- |--------
A        5             
                 10    
B        1             
                 3
C        4
                 150

Make sure you are in "Records" mode (this option is at the top left of the data grid). You should see the rows for each ID are grouped together.

Now use Edit Cells -> Join multi-valued cells on each of the other columns - this should leave you with a single row per record once you have done this for all columns
