合并前： 
<table width="400" border="1"> 
<tr> 
<td>a</td> 
<td>1</td> 
<td>2</td> 
<td>3</td> 
<td>4</td> 
<td>5</td>

合并后：<br />

JS:

復(fù)制代碼代碼如下:

 
<script type="text/javascript"> 
function mc(tableId, startRow, endRow, col) { 
var tb = document.getElementById(tableId); 
if (col >= tb.rows[0].cells.length) { 
return; 
} 
if (col == 0) { endRow = tb.rows.length-1; } 
for (var i = startRow; i < endRow; i++) { 
if (tb.rows[startRow].cells[col].innerHTML == tb.rows[i + 1].cells[0].innerHTML) { 
tb.rows[i + 1].removeChild(tb.rows[i + 1].cells[0]); 
tb.rows[startRow].cells[col].rowSpan = (tb.rows[startRow].cells[col].rowSpan | 0) + 1; 
if (i == endRow - 1 && startRow != endRow) { 
mc(tableId, startRow, endRow, col + 1); 
} 
} else { 
mc(tableId, startRow, i + 0, col + 1); 
startRow = i + 1; 
} 
} 
} 
mc('table1',0,0,0); 
</script>
