Responsive Table With Ellipsis

Responsive Table With Ellipsis

DalderDalder Posts: 28Questions: 11Answers: 1

Hello,

Apologies, another question!

I'd like to use the ellipsis plugin to help limit the number of columns I have to collapse using the responsive extension.

However, if the ellipsis'd column does get collapsed, I would like the full, unshortened version of the data to be visible in the that reflowed data.

Here is an example of what happens currently: http://live.datatables.net/cadecise/3/edit

Is this easily achievable?

Thanks in advance,

Dan

    You can check whether a column is hidden by the responsive extension:
    https://datatables.net/reference/api/column().responsiveHidden()

    Something like this could work:

    table
        .on( 'responsive-resize', function () {
            var colsArray = table.columns().responsiveHidden().toArray();
            var hiddenColsArray = [];
            $.each(colsArray, function(key, value) {
                if ( ! value ) {
                    hiddenColsArray.push(key);
                }
            });        
        })
    

    This would give you an array of column indexes which are hidden by the responsive extension. I guess you'll figure out the rest :smile:

    Thanks for the response, although I'm not entirely sure how that relates to my issue?

    In the meantime, I've come up with a workaround, although it's not particularly clever.

    All I've done is edit the return of the ellipsis renderer to do this:

    return '<span class="ellipsis-shortened" title="'+esc(d)+'">'+shortened+'&#8230;</span><span class="ellipsis-full">'+esc(d)+'</span>';
    

    and have added the following CSS:

    span.ellipsis-full {
        display: none;
    }
    
    span.dtr-data > span.ellipsis-shortened {
        display: none;
    }
    
    span.dtr-data > span.ellipsis-full {
        display: inline;
    }
    

    This does the trick, but it would be preferable to have a JS only fix so simplicity's sake.

    @Allan - sorry to tag you directly, is this something you've been asked about before?

    This does the trick here - it's a tweak from this thread that I did this morning. It's using a custom renderer that allows you to define what tables goes into the child rows. Here, I'm using the raw data again, rather than the rendered data,
