17 * Drop Primary Key/Index
22 * This function returns the horizontal space available for the menu in pixels.
23 * To calculate this value we start we the width of the main panel, then we
24 * substract the margin of the page content, then we substract any cellspacing
25 * that the table may have (original theme only) and finally we substract the
26 * width of all columns of the table except for the last one (which is where
27 * the menu will go). What we should end up with is the distance between the
28 * start of the last column on the table and the edge of the page, again this
29 * is the space available for the menu.
31 * In the case where the table cell where the menu will be displayed is already
32 * off-screen (the table is wider than the page), a negative value will be returned,
33 * but this will be treated as a zero by the menuResizer plugin.
