ну ты, блин, даешь... Dimsi почти готовый пример кинул! ладно, держи:

<SCRIPT LANGUAGE=JavaScript>
var hlColor = "#bec5de";
var hlColorUn = "#ffffff";
var event_MouseDown = false;
var oldCelArchive = new Array();
var UnSel = 0;

function onMouseOver() {
.if(!event_MouseDown) return false;
.srcElem = window.event.srcElement;
.while(srcElem.tagName != "TD" && srcElem.tagName != "TR" && srcElem.tagName != "TABLE")
..srcElem = srcElem.parentElement;
.if(srcElem.tagName != "TD") return;
hilite(srcElem);
}
function hilite(newCel) {
UnSel = 0;
.if(newCel != -1) {
for(i = 0; i < oldCelArchive.length; i++) {
..if(oldCelArchive[i] == newCel) {
UnSel = 1;
oldCelArchive[i] = "";
}
}
. if(UnSel != 1) {
. . newCel.style.backgroundColor = hlColor;
.. oldCelArchive[oldCelArchive.length+1] = newCel;
}
else newCel.style.backgroundColor = hlColorUn;
.}
}
function NoSelected() {
.return false;
.}
function isDown() {
.event_MouseDown = true;
.onMouseOver();
.}
function isUp() {
.event_MouseDown = false;
.}
MyTable.onmousedown = isDown;
MyTable.onmouseup = isUp;
MyTable.onselectstart = NoSelected;
MyTable.onmouseover = onMouseOver;
