After the @multitable command defining the column widths (see
the previous section), you begin each row in the body of a multitable
with @item, and separate the column entries with @tab. 
Line breaks are not special within the table body, and you may break
input lines in your source file as necessary.
  
Here is a complete example of a multi-column table (the text is from The GNU Emacs Manual, see Splitting Windows):
     @multitable @columnfractions .15 .45 .4
     @item Key @tab Command @tab Description
     @item C-x 2
     @tab @code{split-window-vertically}
     @tab Split the selected window into two windows,
     with one above the other.
     @item C-x 3
     @tab @code{split-window-horizontally}
     @tab Split the selected window into two windows
     positioned side by side.
     @item C-Mouse-2
     @tab
     @tab In the mode line or scroll bar of a window,
     split that window.
     @end multitable
     
produces:
| Key | Command | Description | 
| C-x 2 | split-window-vertically | Split the selected window into two windows,
with one above the other. | 
| C-x 3 | split-window-horizontally | Split the selected window into two windows
positioned side by side. | 
| C-Mouse-2 | In the mode line or scroll bar of a window,
split that window. |
