我有以下代码：

table-layout: fixed;
width: 100%;
border-collapse: collapse;
}
td {border: 1px solid #000; padding: 5px; vertical-align: top;}
</style>
<script type="text/javascript">
$(document).ready(function() {
$('#content1').hide();
$('#content2').hide();
$('#content3').hide();
$("input").click(function() {
var thisRow = $(this).closest('tr'); //parent row of the input or whatever is the click trigger
var conDiv = $(this).data("href"); //returns #content1 - id of the content div you want shown
var conH = $(conDiv).height(); //corresponding content div height
var rowH = $(thisRow).height(); // this row height
var newrowH = conH + rowH; //the new row height
var posL = $(thisRow).position().left; // left position that div needs to be
var posT = $(thisRow).position().top + rowH + 5 + 'px'; // top position that div needs to be ** not working properly!!
if ( $(conDiv).is(":visible") ) {
$(thisRow).css({"height" : "auto"});
$(conDiv).css({"display" : "none", "left": "auto", "top" : "auto" });
} else {
//reset all rows to normal height
$("tr").css({"height" : "auto"});
//expand the height of this row
$(thisRow).css({"height" : newrowH});
// reset all content divs.. hide them
$("[id*=content]").css({"display" : "none", "left": "auto", "top" : "auto"});
//show the one you want
$(conDiv).css({"display" : "block", "left": posL, "top" : posT});
}
});
});
