+# Reto #15: ✍️ Dibujando tablas
+
+Al Polo Norte ha llegado ChatGPT y el elfo Sam Elfman está trabajando en una aplicación de administración de regalos y niños.
+
+Para mejorar la presentación, quiere crear una función drawTable que reciba un array de objetos y lo convierta en una tabla de texto.
+
+La tabla dibujada debe representar los datos del objeto de la siguiente manera:
+
+- Tiene una cabecera con el nombre de la columna.
+- El nombre de la columna pone la primera letra en mayúscula.
+- Cada fila debe contener los valores de los objetos en el orden correspondiente.
+- Cada valor debe estar alineado a la izquierda.
+- Los campos dejan siempre un espacio a la izquierda.
+- Los campos dejan a la derecha el espacio necesario para alinear la caja.
+
+Mira el ejemplo para ver cómo debes dibujar la tabla:
+
+```js
+drawTable([
+  { name: 'Alice', city: 'London' },
+  { name: 'Bob', city: 'Paris' },
+  { name: 'Charlie', city: 'New York' }
+])
+// +---------+-----------+
+// | Name    | City      |
+// +---------+-----------+
+// | Alice   | London    |
+// | Bob     | Paris     |
+// | Charlie | New York  |
+// +---------+-----------+
+
+drawTable([
+  { gift: 'Doll', quantity: 10 },
+  { gift: 'Book', quantity: 5 },
+  { gift: 'Music CD', quantity: 1 }
+])
+// +----------+----------+
+// | Gift     | Quantity |
+// +----------+----------+
+// | Doll     | 10       |
+// | Book     | 5        |
+// | Music CD | 1        |
+// +----------+----------+
+```
