After migrating the laravel database, I want to modify the data table field information

After executing

php artisan migrate in laravel, data is also inserted into the database
But now I want to modify the target structure. For example, I want to add a default value of 0 to the title field. If withdrawn, the data will be gone. How can I ensure that the database data is still there? Now you can modify the data table

ps (I tried to create a migration if I added a field, but it didn’t work when I modified the field information)
