修改javascript以無窗體工作？

Question

我想用這個來隱藏/擴展列：

但刪除eveything與窗體有關。 Java腳本函數必須相應地改變，但我沒有任何運氣。有什麼建議麼？
謝謝。

代碼測試和工作。隨意問關於它的問題:)

<script language="javascript"> 

// Set the default "show" mode to that specified by W3C DOM 
// compliant browsers 

var showMode = 'table-cell'; 

// However, IE5 at least does not render table cells correctly 
// using the style 'table-cell', but does when the style 'block' 
// is used, so handle this 

if (document.all) showMode='block'; 

// This is the function that actually does the manipulation 

var States = { }; 

function toggleVis(col){ 

    if (!States[col] || States[col].IsOpen == null) 
    { 
     States[col] = {isOpen : true}; // This assumes the cell is already shown 
    } 

    mode = States[col].IsOpen ? showMode : 'none'; 

    cells = document.getElementsByName(col); 
    for(j = 0; j < cells.length; j++) cells[j].style.display = mode; 

    States[col].IsOpen = !States[col].IsOpen; 
} 

</script> 

<a href="#" onclick="toggleVis('tcol1'); return false;">Toggle 1</a> 
<a href="#" onclick="toggleVis('tcol2'); return false;">Toggle 2</a> 
<a href="#" onclick="toggleVis('tcol3'); return false;">Toggle 3</a> 
<a href="#" onclick="toggleVis('tcol4'); return false;">Toggle 3</a> 

<table border=1> 
<tr> 
<td name="tcol1" class="bold">column 1 text</td> 
<td name="tcol2" >column 2 text</td> 
<td name="tcol3" class="italic">column 3 text</td> 
<td name="tcol4" >column 4 text</td> 
</tr> 
<tr> 
<td name="tcol1" class="bold">column 1 text</td> 
<td name="tcol2" >column 2 text</td> 
<td name="tcol3" class="italic">column 3 text</td> 
<td name="tcol4" >column 4 text</td> 
</tr>
