With a prominence of only 16 metres (52 ft), it is only listed in a few of the recognised categories of mountains in Ireland; it is the 110th–highest peak on the Vandeleur-Lynam Irish scale.

[2][3] Table Mountain is at the apex of a horseshoe-shaped "boggy" massif with its larger neighbours, Camenabologue 758 metres (2,487 ft) and Conavalla 734 metres (2,408 ft) that sit at the head of the Glenmalure valley; all three peaks lie close to the "central spine" of the range as it runs from Kippure in the north, to Lugnaquillia in the south.

[5] On the afternoon of 7 March 1957, between 12:30 and 12:45pm, a Percival Provost training plane crashed into the slopes of Table Mountain in thick fog resulting in the death of its pilot, an Irish Air Corps lieutenant.

[6] The plane had left Baldonnel Aerodrome, Dublin at 11:15am that morning for an intended training flight over the counties of Offaly and Wicklow, but was believed to have lost contact with the control tower shortly after departure.

[6] The explosion was heard by forestry workers on nearby Conavalla Mountain who rushed to assist and were able to raise the alarm.
