Question

I have a table which has a header row and few rows for the body content.

Now these are actually 2 separate tables:

1. for Header
2. for Body content (which is part of another iframe)

I want that the widths should be same for the column header and it’s corresponding body content.

How can I ensure that both the widths are similar and the appearance would be similar as if they are part of the same table?

I am open to both CSS or Javascript fix..

Note: I’ll not be able to use fixed col widths AND neither do I have control to merge into one table…

Maybe something like this? This will make your tables act as if thay where one

    var table1 = document.getElementsByTagName('table')[0].getElementsByTagName('tr');
    var table2 = document.getElementsByTagName('iframe')[0].contentDocument.getElementsByTagName('tr');

    var tr = merge([table1,table2]);
    var padding = 2; //set your padding to make up for difference from offsetwidth vs style width

    var higestWidth = new Array();
    for(var i in tr){
        for(var j in tr[i].childNodes){
        var td = tr[i].childNodes[j];
        if(typeof td == 'object'){
            if(higestWidth[td.cellIndex] == null || higestWidth[td.cellIndex] < td.offsetWidth){
            higestWidth[td.cellIndex] = td.offsetWidth;
            }
        }
        }
        for(var j in tr[i].childNodes){
        var td = tr[i].childNodes[j];
        if(typeof td == 'object'){
            td.setAttribute('width', higestWidth[td.cellIndex] - padding);
            }
        }
        }

Almost forgot im using some of my own functions here, here thay come aswell

        var foreach = function(object,loop){
        for (var key in object) {
            if (object.hasOwnProperty(key)) {
            loop(object[key],key);
            }
        }
    }
    var merge = function(objectCollections){
        var array = new Array();
        foreach(objectCollections,function(objectCollection){
            foreach(objectCollection,function(object){
                array.push(object);
            });
        });
        return array;
    }
