[/code]

after applying datatable plugin for the above table (colspan used table) it gives an error
[quote] Uncaught TypeError: Cannot read property 'style' of undefined in line no.3255 (line mentioned below) [/quote]

[code]
nThs[i].style.width = o.aoColumns[iVis].sWidth;
[/code]

I applied a validation line for that like

[code]
if(nThs[i] !== undefined)
nThs[i].style.width = o.aoColumns[iVis].sWidth;
[/code]

and it works fine!!!!

[quote] Is that ok Alan? If so please recommend it to others to use [/quote]

    I had the same problem and can confirm that the above fix seems to work fine.

    I'm afraid that is not a complete solution. DataTables requires each column to have a unique cell in the header. This _must_ be the case in DataTables at the moment as it needs to be able to address each column individually - for string and filtering. Relaxing this constraint (it is a long term goal) will require some fairly invasive code.
