Example 2: laravel drop column

// To drop a column, use the dropColumn method on the schema builder.
// Before dropping columns from a SQLite database, you will need to add

// composer update command in your terminal to install the library:

Schema::table('users', function (Blueprint $table) {
    $table->dropColumn('votes');
});
