Internet Explorer: CellIndex is Calculated in Display Order (814506)



The information in this article applies to:

  • Microsoft Internet Explorer (Programming) 6 (SP1)
  • Microsoft Internet Explorer (Programming) 5.5 SP2

SYMPTOMS

When you use the cellIndex property when you script a Web page, and then you use the property to reference the next cell in tree order, it may instead reference the next cell in display order and return the wrong value.

WORKAROUND

To work around this behavior, you can compute the correct index value by using a function similar to the following function:
// returns absolute (document) index of cell 
// from table and relative (visible) index of cell 

function getAbsoluteIndex(t,relIndex) 
{ 
countnotvisible=0; 
countvisible=0; 
for (i=0;i<t.cells.length;i++) { 
cell=t.cells(i); 
if (cell.style.display=='none') countnotvisible++; else countvisible++; 
if (countvisible>relIndex) return i; 
} 
return i; 
}
