Here are excerpts from the Code of Canon Law (in English and Latin) that refer to “table” or “altar”. The word “table” (mensa) is used sparingly.
Can. 276 §1 Clerics have a special obligation to seek holiness in their lives, because they are consecrated to God by a new title through the reception of orders, and are stewards of the mysteries of God in the service of His people.
§2 In order that they can pursue this perfection: …
2° they are to nourish their spiritual life at the twofold table of the sacred Scripture and the Eucharist; priests are therefore earnestly invited to offer the eucharistic Sacrifice daily, and deacons to participate daily in the offering;
*Can. 276 - § 1. In vita sua ducenda ad sanctitatem persequendam peculiari ratione tenentur clerici, quippe qui, Deo in ordinis receptione novo titulo consecrati, dispensatores sint mysteriorum Dei in servitium Eius populi. *
§ 2. Ut hanc perfectionem persequi valeant: …
*2_ duplici mensa sacrae Scripturae et Eucharistiae vitam suam spiritualem nutriant; enixe igitur sacerdotes invitantur ut cotidie Sacrificium eucharisticum offerant, diaconi vero ut eiusdem oblationem cotidie participent; *
932 §2 The eucharistic Sacrifice must be carried out at an altar that is dedicated or blessed. Outside a sacred place an appropriate table may be used, but always with an altar cloth and a corporal.
932 § 2. Sacrificium eucharisticum peragendum est super altare dedicatum vel benedictum; extra locum sacrum adhiberi potest mensa conveniens, retentis semper tobalea et corporali.
Can. 1235 §1 The altar or table on which the eucharistic Sacrifice is celebrated is termed fixed if it is so constructed that it is attached to the floor and therefore cannot be moved; it is termed movable, if it can be removed.
§2 It is proper that in every church there should be a fixed altar. In other places which are intended for the celebration of sacred functions, the altar may be either fixed or movable.
Can. 1235 - § 1. Altare, seu mensa super quam Sacrificium eucharisticum celebratur, fixum dicitur, si ita exstruatur ut cum pavimento cohaereat ideoque amoveri nequeat; mobile vero, si transferri possit. [Please note the punctuation of the Latin text of 1235.1 which is not accurately represented in the English text.]
§ 2. Expedit in omni ecclesia altare fixum inesse; ceteris vero in locis, sacris celebrationibus destinatis, altare fixum vel mobile.
Can. 1236 §1 In accordance with the traditional practice of the Church, the table of a fixed altar is to be of stone, indeed of a single natural stone. However, even some other worthy and solid material may be used, if the Episcopal Conference so judges. The support or the base can be made from any material.
§2 A movable altar can be made of any solid material which is suitable for liturgical use.
*Can. 1236 - § 1. Iuxta traditum Ecclesiae morem mensa altaris fixi sit lapidea, et quidem ex unico lapide naturali; attamen etiam alia materia digna et solida, de iudicio Episcoporum conferentiae, adhiberi potest. Stipites vero seu basis ex qualibet materia confici possunt. *
§ 2. Altare mobile ex qualibet materia solida, usui liturgico congruenti, exstrui potest.
Can. 1237 §1 Fixed altars are to be dedicated, movable ones either dedicated or blessed, according to the rites prescribed in the liturgical books.
§2 The ancient tradition of placing relics of Martyrs or of other Saints within a fixed altar is to be retained, in accordance with the rites prescribed in the liturgical books.
*Can. 1237 - § 1. Altaria fixa dedicanda sunt, mobilia vero dedicanda aut benedicenda, iuxta ritus in liturgicis libris praescriptos. *
§ 2. Antiqua traditio Martyrum aliorumve Sanctorum reliquias sub altari fixo condendi servetur, iuxta normas in libris liturgicis traditas.
Can. 1238 §1 An altar loses its dedication or blessing in accordance with Can. 1212.
§2 Altars, whether fixed or movable, do not lose their dedication or blessing as a result of a church or other sacred place being made over to secular usage.
*Can. 1238 - § 1. Altare dedicationem vel benedictionem amittit ad normam can. 1212. *
§ 2. Per reductionem ecclesiae vel alius loci sacri ad usus profanos, altaria sive fixa sive mobilia non amittunt dedicationem vel benedictionem.
Can. 1239 §1 An altar, whether fixed or movable, is to be reserved for divine worship alone, to the exclusion of any secular usage.
§2 No corpse is to be buried beneath an altar; otherwise, it is not lawful to celebrate Mass at that altar.
*Can. 1239 - § 1. Altare tum fixum tum mobile divino dumtaxat cultui reservandum est, quolibet profano usu prorsus excluso. *
§ 2. Subtus altare nullum sit reconditum cadaver; secus Missam super illud celebrare non licet.
Can. 1309 Where a fitting reason exists, the authorities mentioned in Can. 1308 have the power to transfer Mass obligations to days, churches or altars other than those determined in the foundation.
Can. 1309 - Iisdem auctoritatibus, de quibus in can. 1308, potestas insuper competit transferendi, congrua de causa, onera Missarum in dies, ecclesias vel altaria diversa ab illis, quae in fundationibus sunt statuta.
