# Limit the allowed data set size by number of cells
|
|
|
|
|
|
|
|
|
|
This function may act to guard a hosted app against very large data sets
|
|
|
|
|
in addition to the file size limitations. The function will limit the
|

|
|
|
data set by dropping rows. If limit is set to 0 or NULL, the original
|
|
|
|
|
data set is returned.
