TIP
You can use the MIB Tree panel to determine which objects are tabular and which are not:
objects which are part of a table will descend from a blue folder (which will have a “T” on
it, and a name which will almost always include the word “table”); objects which are not
will descend directly from a yellow folder. (Note: There may be one or more yellow
folders in between the blue folder which contains the table and the leaf object you wish to
use; however, those objects are still part of the table.)
