A Two Column Example

The L A T E X Team

Abstract

An example document showing automatic tagging of typical structures found in a L A T E X document, including titles, sections, theorems, lists, citation lists and mathematics. A two column layout is used, the tagging enables the reading order to correctly follow the flow of text through the columns.

ment just uses standard L A T E X markup that would be used in any L A T E X document since the 1980s.

1 Introduction

This document shows a typical two-column document incorporating tables, figures and mathematics.

Apart from two commands at the start to enable tagging, and a small amount of additional markup to give alternative texts for graphics inclusion, and to specify the heading rows of tables. 1 The document

1 The current tagging markup for tables is temporary and a new interface for tagging tables will be developed.

2 Document structures

2.1 Mathematics

Let p be a prime, then

n^p = n \pmod p

An aligned set of equations:

f(x) = \sin x + \cos x \quad f'(x) = \cos x - \sin x \quad (2.1)

g(x) = 2 \cos x \quad g'(x) = -2 \sin x \quad (2.2)

Matrices.

\begin{pmatrix} 1 & 2 \\ 3 & 4 \end{pmatrix} \begin{pmatrix} 1 & 1 \\ 0 & 1 \end{pmatrix} = \begin{pmatrix} 1 & 3 \\ 3 & 7 \end{pmatrix}

2.2 Lists

Lists often occur in documents.

Here we reference item 2.

2.3 Figures and Tables

Small images may be shown inline small image icon and small tables may be shown within the paragraph:

Example
Name Value
This 11
That 2

Marginal notes are usually placed in the outer margin.

Larger figures such as Figure 1 are usually placed in a float to be positioned at a suitable place to help with column and page breaking.

2.4 Theorems

Theorem 1 (Fermat's Last Theorem). If n > 2 , then there are no non-zero integers a, b, c such that a^n + b^n = c^n .

2.5 Verbatim

Some documents require verbatim code blocks to be displayed. 

main( ) {
    printf("hello, world");
}
