How to merge rows and sum them?

How can we merge rows of a table as shown below:

XY     
STATE_1 1 STATE_1 6896 
STATE_1 2 STATE_2 7 
STATE_1 3 STATE_3 22 
STATE_2 4 STATE_4 861 
STATE_2 3 STATE_2 9494 
STATE_3 2 STATE_1 37412 
STATE_3 5 STATE_2 4 
STATE_3 10 STATE_3 18 
STATE_3 5 STATE_4 353 
STATE_4 576 STATE_2 9494 
STATE_4 33 STATE_1 3737 
STATE_4 25 STATE_2 44 
STATE_4 97     
STATE_4 54     
STATE_4 76     
STATE_2 94     
STATE_1 37     
STATE_2 4     

 

1. First group the continuous occurrence of rows

2. Calculate the sum of sequential occurrence of STATE_1 to STATE_4

 

Pfa the sample table for your reference

Re: How to merge rows and sum them?

I solved the problem using 2 new formula columns

The Group column formula just creates a grouping number when :Big Value is detected

If( Row() == 1, theGroup = 0 );
If( Is Missing( :Big Value ) == 0,
	theGroup
	++);
theGroup;

The Sum column formula just looks one row ahead, and if it detects a non missing value for :Big Value, it adds up the sums for both :Value and :Big Value for the current Group and then adds them together

If( Is Missing( :Big Value[Row() + 1] ) == 0,
Sum( Col Sum( :Value, :Group ), Col Sum( :Big Value, :Group ) ),
If( Row() == N Rows( Current Data Table() ) & Is Missing( :Big Value ) == 0,
Sum( :Value, :Big Value )
)
)

Attached is the data table I used
