    Arrays line items up in columns 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 and l (left) for each column to describe how it will be formatted

  • What do the pieces of LaTeX, \left and \right, respectively mean?
    \left and \right are used for delimiters when they have to change the size dynamically depending on the content Consider the following example:
  • \left \right (LaTeX2e unofficial reference manual (January 2025))
    The \left \right pair affect the horizontal spacing of the enclosed formula, in two ways The first is that in \( \sin(x) = \sin\left(x\right) \) the one after the equals sign has more space around the x That’s because \left( \right) inserts an inner node while ( ) inserts an opening node The second way that the pair affect the
  • 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
