        $table->string('N_MARK')->nullable();
        $table->string('ZAV_NOMER')->nullable();
        $table->string('DIAM')->nullable();
        $table->string('N_MISK')->nullable();
        $table->text('DATA_VST')->nullable();
        $table->text('DATA_POV')->nullable();
        $table->text('DATA_NAST_POV')->nullable();
        $table->string('KIL_MISIAC')->nullable();
        $table->string('POP_POK')->nullable();
        $table->string('OST_POK')->nullable();
        $table->string('TIP')->nullable();
        $table->string('KON_POK')->nullable();
        $table->text('DATA_KON_POK')->nullable();
        $table->text('DATA_N_PLOMB')->nullable();
        $table->string('N_PLOMB')->nullable();
        $table->timestamps();
    });
