My question is: Why inductance value didn't respect the table ?
Since you did not upload a schematic, it is really hard to tell.

It is possible that your line with the table is too long.? Did you enter the line (the one starting with B1) as a SPICE Directive (SPICE Netlist)?? Or was it a Bv-symbol with the table's data entered in the Value, Value2, SpiceLine, and SpiceLine2 lines?? I am aware of (I think) a 255 character limit when going from LTspice symbols to Netlist code, which is caused by a Microsoft Windows limit.

If the line was in Netlist code or SPICE Directive, was there any line-wrap in the editor you used?

Can you diagnose the circuit yourself?? Does the B-source correctly map the input current I(V2) to the voltage V(tb)?

Did you correctly implement the behavioral inductance with the FLUX=... formula?? How did you determine the effective inductance as a function of time?? (I'm assuming from your question that this was not an .AC simulation.)
