If the system is all VHF, and never uses any 850 or 760 MHz voice frequencies, then you can leave those entries out.
The PRO-96 doesn't use, directly, the "table identifier". Instead, it uses the 16-bit "channel" field in the call grants/updates as an explicit channel number (according to the P25 docs, that 16-bit field is really broken into two sub-fields: a 4-bit table identifier and a 12-bit channel number).
This is why you have to use the "channel Hi" and "channel Lo" values when entering data for the PRO-96. The scanner takes the 16-bit channel number in the grant and compares it to those 2 fields in each of the 6 table entries. As soon as it finds an entry that "contains" the target channel number, it uses the entry's base/offset/step values to calculate the voice frequency.
Each P25 "table identifier" represents 4096 consecutive, 16-bit channel numbers: table 00 = channels 0 - 4095, table 01 = channels 4096 - 8191, etc.
The order in which you enter the data in Win96 is not important. The PRO-96 doesn't use the "index" at all. Instead, as mentioned above, it does explicit comparisons using each entry's "Lo" and "Hi" values.
