Hi
Good catch! Thanks for repothing this issue. I will investigate

as a quick workaround duplicate empty thead columns into table
http://jsfiddle.net/kx9fa0se/10/

I didn't think about it.
I added several td to the "top-space" tr when "clusterChanged" event triggers.
Your workaround is better.

:D

Yes It's a bit hacky but It does it !

This workaround breaks the "no data" row which needs a colspan to be as larger as the entire table.

@jbanety sad to hear that
Since you've already forked project, add temporarily extra line here

td = document.createElement('td');
td.colSpan = 100;

This will force td to be full width. I'll think about better solution

@NeXTs, better would be to add some callback, e.g. generateEmptyRow and pass created element to it:

var callbacks = options.callbacks;
callbacks.generateEmptyRow && callbacks.generateEmptyRow(empty_row);

I'm planning to rethink clusterize structure and instead of additional tags, use paddings/margins
