Adding Columns

Run the suggested code directly from Tinker.

Schema::table('<YOUR TABLE>', function ($table) {
    $table->string('name')->nullable()
        ->after('<DESIRED COLUMN>'); // add after desired column
});

Renaming Columns

Run the suggested code directly from Tinker.

Schema::table('<YOUR TABLE>', function ($table) {
    $table->renameColumn('<FROM>', '<TO>');
});

Removing Columns

Run the suggested code directly from Tinker.

Schema::table('<YOUR TABLE>', function ($table) {
   $table->dropColumn('<DESIRED COLUMN>');
});

You may drop multiple columns from a table by passing an array of column names to the dropColumn method:

Schema::table('<YOUR TABLE>', function ($table) {
   $table->dropColumn(['<DESIRED COLUMN>', '<DESIRED COLUMN 1>']);
});

Note

You can also use arrow functions

Schema::table('<YOUR TABLE>', fn($t)=> $t->string('<DESIRED COLUMN>')->nullable());
