要完成此效果把如下代码加入到区域中
<script language=javascript>
var cellwidth=10; // EACH "CELL" WIDTH IN PIXELS
var cellheight=10; // EACH "CELL" HEIGHT IN PIXELS
var fontsize=11; // FONT SIZE OF THE NUMBERS. SETTING THIS TOO BIG CAUSES
UNDESIRED EFFECTS.
var fontcolor="33ff33"; // ENTER ANY HTML OR RGB COLOR CODE
var fontstyle="bold"; // ENTER EITHER BOLD, ITALICS, NONE
var oncolor="red"; // COLOR OF ACTIVE CELLS
var offcolor="lightgrey"; // COLOR OF INACTIVE CELLS
//************** DO NOT EDIT BEOND THIS POINT *************//
