创建新移植：运行以下Artisan命令以创建新移植文件：

php artisan make:migration add_pending_to_status_enum_in_table_name --table=your_table_name

字符串
下面是迁移文件中的up和down方法的示例：

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
use Illuminate\Support\Facades\DB;

class AddPendingToStatusEnumInTableName extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        DB::statement("ALTER TABLE your_table_name MODIFY COLUMN your_enum_column ENUM('paid', 'unpaid', 'pending', 'free')");
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        DB::statement("ALTER TABLE your_table_name MODIFY COLUMN your_enum_column ENUM('paid', 'unpaid', 'free')");
    }
}

你的迁移文件应该是这样的

public function up(): void
{
    Schema::table('payment_spps', function (Blueprint $table) {
        $table->enum('January', ['paid', 'unpaid', 'pending', 'free',])->default('unpaid')->change();
        // other columns ...
    });
}

字符串
如果不行，你可以试试这个

public function up(): void
{
    Schema::table('payment_spps', function (Blueprint $table) {
        DB::statement("ALTER TABLE payment_spps MODIFY COLUMN `January` ENUM('paid', 'unpaid', 'pending', 'free')");
    });
}

如果要使用它设置默认值

public function up(): void
{
    Schema::table('payment_spps', function (Blueprint $table) {
        DB::statement("ALTER TABLE payment_spps MODIFY COLUMN `January` ENUM('paid', 'unpaid', 'pending', 'free') default('unpaid') ");
    });
}
