The Break footer
block is an optional block found in the reports created with the report editor. This block is created if a break is requested on a sort argument. The Break header
block necessarily exists if this block exists.
This block is run whenever the value of the sort argument changes, after the last iteration of the Body block for a value of the sort argument. In most cases, it contains the counter or total controls for the records corresponding to the sort argument.
Note: The Break header block and the Break footer block cannot be dissociated. However, one of these blocks can be made invisible (in the description window of the block or by ..可见).
See Describing the report blocks
for more details.
