Open a document with a table, click anywhere in the table, then move the pointer over the letter above the column by which you want to sort.
Click the arrow that appears next to the column letter, then choose a sorting option:
Sort Ascending: Sort the data in alphabetical order (A to Z) or by increasing numerical values.
Sort Descending: Sort the data in reverse–alphabetical order (Z to A) or by decreasing numerical values.
In columns containing both text and numbers, ascending order sorts numbers before text (for example, 1a, 1b, 2a, a1, b1). Ascending order also places Boolean (true/false) cells after cells sorted alphabetically or numerically, and places blank cells at the bottom of the column.
Tip: Table columns don’t sort independently from each other—all the cells in a row stay together when you sort a column. If you want to sort a column separately, first sort the column, then Merge or unmerge table cells in Pages on Mac
