The idea originally came to a group of engineering students, and hundreds of volunteers on Friday took part in organizing the event, which could seat up to 10-thousand people for the Iftar dinner, which follows the daily Ramadan fasting.
Ossama Barakat, one of the organisers of the event, said the 4.5 kilometre (2.7 mile) long table had surpassed in length the previous record-holder Italy's table, which he said was two kilometres long (1.2 miles).
Guinness World Record officials later handed organisers a certificate recognising the new record.
Barakat said he hoped the event would attract tourists and improve Alexandria's image.
During Ramadan, the holiest month in Islam, millions of Muslims refrain from eating, drinking, smoking and … from dawn to dusk.
