Making tables can be one of the most complex TeX tasks, but with the Table Macro Package, constructing even the most elaborate tables is a snap. Table also works with LaTeX. Headings may be placed over single columns or groups of columns. Table entries may contain equations or several rows of text. Horizontal and vertical lines may be drawn wholly or partially across the table. The Table Manual contains many examples and exercises.
