Attempt to display the following table

2	A	1
m|		x	:n

as an in-line element. A table as an in-line element is possible, but only if you modify the surrounding paragraph to be inline as well.

The same but with the central character outside of a table

2

m|

A

1
x	:n

looks nearly the same, although the central character is more consistent with surrounding text.

Usage

Possible user formatting: "^2_m| Abar ^1_x:n¬"?

Replacement glyphs:

Code	Display
adue	ä
Adue	Ä
@bar	@

...where "@" represents any character.

Extension

Use cases:

• Annuity (a)
• Accumulation (s)
• Assurance (A, (IA))
• Premium (P)
• Commutation functions (D, N, S, C, M, R) to allow for m-thly frequencies

Not required for: i, d, v, l, q, p, μ

Need to allow for multiple contingent events:

• x for whole of life
• x:n¬ for endowment
• x'1:n¬ for term
• x:n¬'1 for pure endowment
• x:y:n¬ for joint-life endowment

Formatting issues

Problems with clashing lines: ä_x + ä_n = ä_x:n + ä_x:n

An n-year-guaranteed annual annuity due:

ä
	x:n
