Fix: Ensure first element is retrieved from associative array

[egyjs]

What Changed:
Replaced:

$this->createTable($tableName, $rows[0]);

with:

$this->createTable($tableName, array_values($rows)[0]);

Why:
In cases where $rows is not zero-indexed (e.g. after a filter() or manually assigned keys), trying to access $rows[0] throws:

ErrorException: Undefined array key 0

Example:

$rows = [
    5 => ['id' => 1, 'name' => 'A'],
    6 => ['id' => 2, 'name' => 'B'],
];

Accessing $rows[0] will trigger the exception above because key 0 doesn't exist.

Fix:
array_values($rows)[0] reindexes the array numerically, so the first element is always at index 0 regardless of the original keys.

This ensures the code works correctly with any numerically keyed array.
