jQuery highlighting selected columns only in a table

Question

I see this post on highlighting even columns but can I highlight only selected columns?

Here is the code they use:

$(\"table.Table22 > tbody >          


        

Answer 1

have you concidered using colgroups instead of adding classes to every cell?

i only recently started to see the power of colgroups myself, and they work like this:

.highlight {
    background-color: yellow; 
 }

     

    	   
    	       
    	       
    	       
    	       
    	       
    	   
    	    

    	       

    	           
header1
    	           
header2
    	           
header3
    	           
header4
    	           
header5
    	       
    	    
    	    

    	       

    	           
cell a
    	           
cell b
    	           
cell c
    	           
cell d
    	           
cell e
    	       
        	

     
this would render a table with 5 columns, where 1 column has css class to highlight the first col. so actually the only thing you have to do then, add a function to the hover of each cell, to just add the highlighting class to the corresponding colgroup.
there is a complete videoguide you can find right here:table fix header, and row + column highlighting.
