d Group 18, the noble gases, were not discovered at the time of Mendeleev's original table. Later (1902), Mendeleev accepted the evidence for their existence, and they could be placed in a new "group 0", consistently and without breaking the periodic table principle. r Group name as recommended by IUPAC.
It can be difficult to find the source data just from a link to the entry page of a reference. Please provide a path to the specific source data used in a table. Otherwise WP:V says the unsourced material can be deleted from the article. WP:V: "Readers must be able to check that any of the information within Wikipedia articles is not just made ...
Tables are a common way of displaying data. This tutorial provides a guide to making new tables and editing existing ones. For guidelines on when and how to use tables, see the Manual of Style. The easiest way to insert a new table is to use the editing toolbar that appears when you edit a page (see image above).
[9] [citation needed] The Tits group is the (n = 0)-member 2 F 4 (2)′ of the infinite family of commutator groups 2 F 4 (2 2n+1)′; thus in a strict sense not sporadic, nor of Lie type. For n > 0 these finite simple groups coincide with the groups of Lie type 2 F 4 (2 2n+1), also known as Ree groups of type 2 F 4.

The Irwin–Hall distribution is the distribution of the sum of n independent random variables, each of which having the uniform distribution on [0,1]. The Bates distribution is the distribution of the mean of n independent random variables, each of which having the uniform distribution on [0,1]. The logit-normal distribution on (0,1).
Another method of grouping the data is to use some qualitative characteristics instead of numerical intervals. For example, suppose in the above example, there are three types of students: 1) Below normal, if the response time is 5 to 14 seconds, 2) normal if it is between 15 and 24 seconds, and 3) above normal if it is 25 seconds or more, then the grouped data looks like:
All data tables need a table caption that succinctly describes what the table is about. [ WCAG 2 ] It plays the role of a table heading, and is recommended as a best practice. [ 2 ] You would usually need some kind of heading or description introducing a new table anyway, and this is what the caption feature exists for.
