array must be inside a math environment; this could be fixed by enclosing it in \[ \] the alignment within the array must be specified; for this, \begin{array}{l} would work the primes (input as apostrophes) are defined to be superscripts, so the explicit ^ is unwanted
- array (LaTeX2e unofficial reference manual (January 2025))
For instance, \begin{array}{rcl} \end{array} gives three columns: the first flush right, the second centered, and the third flush left See tabular for the complete description of cols and of the other common features of the two environments, including the optional pos argument
- Array Environment – Using Latex in Pressbooks
Here are some basic steps for making arrays (a) Type \begin{array} (b) Use an argument to describe how you want your table to be justified Immediately following the \begin{array} command, add a set of brackets Inside the brackets, use the letters r (right), c (center), and l (left) for each column to describe how it will be formatted
- Latex Array Command - GitHub Pages
$latex \begin{array}[r]{c1 cn} In this case the value of r specifies how each row is aligned where t means align the top, c means align the center, and b means align the bottom For example, the input $latex \begin{array}[t]{cc} \begin{array}{c} a \\ b \end{array} \begin{array}{cc} a b \end{array} \end{array} $$
- Missing \right inserted - Overleaf, Online LaTeX Editor
This error happens when typesetting math if the \left command is used but the corresponding \right is missing This article talks about common causes of this error and how to fix them The \left and \right commands typeset dynamically-sized delimiters and must be used together, within mathematical material, in the form
- Display math in \begin{array} - TeX - LaTeX Stack Exchange
array is designed for matrices and other tables of values It uses \textstyle and does not give correct spacing for relations or binary operators Your example shows this in \sum and the spacing for -and + as unary prefix with no space AMS alignments are designed to address these issues
- left aligning the conditional statement inside an array
They are right aligned because you have {array}{lr} change that to {array}{ll} to left align both columns But generally it is best not to use array for laying out whole equations, it is designed for matrices arrays
- Bad interaction between `\left` and `\begin {array} [b]`?
When you use \begin{array}[b], you switch the anchor point of the array to the lowest last row Then, when you add a brace, that brace necessarily has a centered (vertically) anchor point with equal length above and below to cover its contents That's why you have a blank part below the array - the result of a symmetrical brace
