I'll use a few examples to show you how to quickly remove columns using migration. Here is an example that will assist you.

class ChangePostsTableColumn extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::table('posts', function (Blueprint $table) {
$table->dropColumn('body');
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
}
}
Example 2: Remove Multiple Column using Migration
Database\Migrations\ChangePostsTableColumn.
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;

*/
public function up()
{
Schema::table('posts', function (Blueprint $table) {
$table->dropColumn(['body', 'title']);
});
}
/**

*/
public function down()
{
}
}
Example 3: Remove Column If Exists using Migration

public function up()
{
if (Schema::hasColumn('posts', 'body')){
Schema::table('posts', function (Blueprint $table) {
$table->dropColumn('body');
