Can Sequelize map existing tables?

this is the definition of my model

const Sequelize = require("sequelize");
const sequelize = require("../../db/db_tp.js");

const manage_notice = sequelize.define("manage_notice", {
    nid: {type:Sequelize.INTEGER,primaryKey: true,autoIncrement: true},
    nname:Sequelize.STRING(20),
    nmaincolor:Sequelize.STRING(20),
    nothercolor:Sequelize.STRING(20),
    nshareicon:Sequelize.STRING(100),
    nsharetitle:Sequelize.STRING(30),
    nsharecontent:Sequelize.STRING(50),
  })

  manage_notice.sync({force: false}).then(function () {
    // Table created
    manage_notice.findAll().then(result => {
        
    })
    
  });

module.exports = manage_notice;

because there is a table with a certain amount of data before, but every time it is mapped, it is because the table name repeats and creates a new table with a tail added to it.

if so, isn"t it troublesome to change the table structure? Do you have to think about all the field structures in the first place?
