It depends - see below.

Correct - it is already defined as part of DisMan.

I believe the DisMan table can only moitor scalars.

The same way you would implement a get for the same object. If you
want to emit the notification for certain values of the object, or just
whenever it changes, put the check in the commit phase of your set handler.

Nonsense! The DisMan Event MIB can monitor both scalars and table elements quite happily. *All* the examples discussed in the documentation are table-based monitors - both the linkUp/Down processing (monitoring elements from the ifTable), and the UCD-specific "defaultMonitors" configuration (monitoring elements from the various UCD tables). Please re-read the descriptions in RFC 2981 of how the Event MIB works, paying particular attention to the discussion of objects vs instances.

Nonsense!
The DisMan Event MIB can monitor both scalars and table
elements quite happily. *All* the examples discussed in
the documentation are table-based monitors - both the
linkUp/Down processing (monitoring elements from the ifTable),
and the UCD-specific "defaultMonitors" configuration
(monitoring elements from the various UCD tables).
Please re-read the descriptions in RFC 2981 of how the Event
MIB works, paying particular attention to the discussion of
objects vs instances.

and how the sentv2trap deal with when the monitor object is one column of the
row?
That is to say,How I can mapping the data in the send_uitUPSTraps_trap( void )
function,especially the
upsXID,upsStatus are the columns in the table?
Should I just do the thing use DisMan way and config the snmpd.conf?
int
send_uitUPSTraps_trap( void )
{
netsnmp_variable_list *var_list = NULL;
oid uitUPSTraps_oid[] = { 1,3,6,1,4,1,30901,2090,7000,5,0,22 };
oid upsXID_oid[] = { 1,3,6,1,4,1,30901,2090,7000,2,2,4,1,1,2, /* insert
tableindex here */ };
oid upsStatus_oid[] = { 1,3,6,1,4,1,30901,2090,7000,2,2,4,1,1,8, /* insert
tableindex here */ };
/*
* Set the snmpTrapOid.0 value
*/
snmp_varlist_add_variable(&var_list,
snmptrap_oid, OID_LENGTH(snmptrap_oid),
ASN_OBJECT_ID,
uitUPSTraps_oid, sizeof(uitUPSTraps_oid));
/*
* Add any objects from the trap definition
*/
snmp_varlist_add_variable(&var_list,
upsXID_oid, OID_LENGTH(upsXID_oid),
ASN_OCTET_STR,
/* Set an appropriate value for upsXID */
NULL, 0);
snmp_varlist_add_variable(&var_list,
upsStatus_oid, OID_LENGTH(upsStatus_oid),
ASN_INTEGER,
/* Set an appropriate value for upsStatus */
NULL, 0);
/*
* Add any extra (optional) objects here
*/
/*
* Send the trap to the list of configured destinations
* and clean up
*/
send_v2trap( var_list );
snmp_free_varbind( var_list );
return SNMP_ERR_NOERROR;
