Also, if the table has cell spacing (and thus border-collapse=separate), meaning that cells have separate borders with a gap in between, that gap will still be visible. A cruder way to align columns of numbers is to use a figure space   or  , which is intended to be the width of a numeral, though is font-dependent in practice:

In mathematics, Rathjen's psi function is an ordinal collapsing function developed by Michael Rathjen. It collapses weakly Mahlo cardinals M {\displaystyle M} to generate large countable ordinals . [ 1 ]
In mathematical logic and set theory, an ordinal collapsing function (or projection function) is a technique for defining (notations for) certain recursive large countable ordinals, whose principle is to give names to certain ordinals much larger than the one being defined, perhaps even large cardinals (though they can be replaced with recursively large ordinals at the cost of extra technical ...

And the function θ γ is defined to be the function enumerating the ordinals δ with δ∉C(γ,δ). The problem with this system is that ordinal notations and collapsing functions are not identical, and therefore this function does not qualify as an ordinal notation. An associated ordinal notation is not known.
For more complex table structures, Visual editor offers cell-merging operations; see details here.. In addition, it is usually possible to add or import a table that exists elsewhere (e.g., in a spreadsheet, on another website) directly into the visual editor by:
There are several slightly different sorts of collapsing algebras. If κ and λ are cardinals, then the Boolean algebra of regular open sets of the product space κ λ is a collapsing algebra. Here κ and λ are both given the discrete topology. There are several different options for the topology of κ λ. The simplest option is to take the ...
