title: Sum values in datatable column til 0 is found (subtotal)
body: <p>I have a datatable with the following values:</p>
  
  <p>Name1   |   1</p>
  
  <p>Name1   |   1</p>
  
  <p>Name1   |   1</p>
  
  <p>Name1   |   0</p>
  
  <p>Name1   |   1</p>
  
  <p>Name1   |   0</p>
  
  <p>Name2   |   1</p>
  
  <p>Name2   |   0</p>
  
  <p>and I want to end up with the following values in another datatable, basically subtotaling the column until a zero is found</p>
  
  <p>Name1   |   3</p>
  
  <p>Name1   |   1</p>
  
  <p>Name2   |   1</p>
  
  <p>I can put the original data into an array, a list, it doesn't matter, I just can't figure out how to do this!</p>
  
  <p>I haven't tried anything that came close, so I don't have any code to add.</p>
  
  <p>Thank you!</p>
