Mark Blocks in Table

Inspects two columns in a table. One column denotes the start of the block and the second denotes the end. Specifying the same column for both is allowed.

The component looks for a start marker and an end marker in the respective columns. For all the rows in between the start and end markers, a unique block number is assigned in the appended output column
