NAME: المائدة, Al-Ma’ida.

Name taken from Verse 112 where there is a mention of the “Table Spread”.

١١٢  إِذْ قَالَ الْحَوَارِيُّونَ يَا عِيسَى ابْنَ مَرْيَمَ هَلْ يَسْتَطِيعُ رَبُّكَ أَنْ يُنَزِّلَ عَلَيْنَا مَائِدَةً مِنَ السَّمَاءِ ۖ قَالَ اتَّقُوا اللَّهَ إِنْ كُنْتُمْ مُؤْمِنِينَ

112  [And remember] when the disciples said, “O Jesus, Son of Mary, can your Lord send down to us a table [spread with food] from the heaven? [Jesus] said,” Fear Allah, if you should be believers.”

But It does not mean that this name is the actual topic discussed in the whole Surah. It is just a reference and mark/symbol to distinguish this Surah from others as is with most other Surahs of Quran. While there are diversified topics discussed in these Surahs.
