# Table digits

Table digits (top) as opposed to proportionally set digits (bottom)

Table numbers are characterized by a uniform thickness  - usually a half-square  - (or the possibility of designing them with the same thickness ) and uniform front and rear width ( meat ). They are therefore equivalent ( equidistant ) numeric representations. This makes them more suitable for tables in which numbers should be right-aligned below one another. The number  1 is particularly problematic here , as it takes up significantly less space, but also uses the same width as the remaining numbers. The English name is Tabular Figures .

Tabular numbers can be both old style and uppercase numbers , although the latter is much more common today.

## Half-fourth digits

Half-square digits have a spatial extension of half a square in width (if the font size is 10 pt, the digit has a thickness of 5 pt). Due to the fixed width of each character ( non-proportional font ) and thus better clarity, they are mainly used for setting columns of numbers or tables with rows of numbers.

## Implementation in computer systems

### typewriter

The easiest and most robust way is to choose a font of the same thickness; this is regularly a typewriter font . Can reach this by selecting an appropriate font, such as Courier New , or in HTML by

• `<span style="font-family:monospace">0123456789</span>` or simply
• `<tt>0123456789</tt>`.

The digits have simple ASCII coding (U + 0030 – U + 0039).

### Unicode

The property "table number" is referred to in Unicode with the expression MATHEMATICAL MONOSPACE DIGIT. In the Unicode block mathematical alphanumeric symbols are defined at the positions `1D7F6`- `1D7FF`the digits 0–9.

If you want to copy and paste this data into a calculation formula (for example for a spreadsheet ), it usually cannot be interpreted - ASCII codes are expected.

In the unicode block half-width and full-width forms there is another variety. Here, among other things, western numerals are offered in half and full width - however, this is used to embed Asian characters and takes their style and width. Fonts with these encodings are not to be expected on European computers; their use is not to be expected.

### Fonts

According to the English tabular figures , suitable fonts are usually identified by the abbreviation TF, corresponding OpenType fonts contain the various digit forms. It is important to distinguish between fonts that the ASCII positions `30`- `39`contain correspondingly shaped figures, and those in which they are at the points `1D7F6`- `1D7FF`are located, while at `30`- `39`the usual proportional figures are.

### compatibility

Use on your own system is unproblematic. However, if a document is to be displayed somewhere else, it must be assumed that fonts and encodings are not defined there, so that the numbers cannot be read.

• The fonts are to be embedded in PDF documents.
• The typographical table number is unsuitable for websites; the codes 1D7F6-1D7FF will regularly be illegible to the unknown reader. Typewriter font should be used here.

### Digit-wide line

The figure dash , U + 2012, belongs in the context of the table numbers . In German-language typography, it is only permitted in the context of the same-headed number representation described here; in the Anglo-American area it is also used for the notation of telephone numbers.

There is also a wide digits space , U + 2007 ( figure space ) of the protected space belongs.

In this way, in the context of tables, the numbers can be arranged with the same thickness; However, full stop and comma are missing.
