Bukhari

Hadith Commentary:
(1)
Throughout the entire life of the Messenger of Allah (sallallahu alayhi wa sallam), it never happened that he and his family ate their fill of barley bread for two consecutive days, nor did they ever eat fine bread (thin chapati). Rather, the Messenger of Allah (sallallahu alayhi wa sallam) supplicated to Allah, saying:
“O Allah! Make the sustenance of the family of Muhammad just sufficient for their needs.”
(Sahih al-Bukhari, Kitab al-Riqaq, Hadith: 6460)
That is, sustenance should be only to the extent that the system of life continues.

(2)
The same was the condition of the noble Companions (radi Allahu anhum) of the Prophet (sallallahu alayhi wa sallam). For example, Abu Hurairah (radi Allahu anhu) once passed by some people who had a roasted goat in front of them.
They invited him to eat, but Abu Hurairah (radi Allahu anhu) refused to eat and said:
The Messenger of Allah (sallallahu alayhi wa sallam) departed from this world, but he never ate his fill of wheat bread.
(Sahih al-Bukhari, Kitab al-At‘imah, Hadith: 5416)

Hadith Commentary:
It is permissible to eat on a table, but this manner is contrary to the Sunnah. Simplicity is what is beloved in Islam.

Hadith Commentary:
(1)
"Sakarjah" refers to the cup in which digestive aids (jawarish, etc.) were kept. The Messenger of Allah (sallallahu alayhi wa sallam) used to eat very little, so there was no need for digestive aids (jawarish). Furthermore, such types of vessels were used by arrogant people, and similarly, the use of tables and the like was also common among the wealthy.

According to our inclination, eating food on a table is permissible, but the Sunnah method is to spread a cloth (dastarkhwan) on the ground and eat upon it. And Allah knows best.
