any updates on ETA for this one?
Hi
Do we have an update on the call. it is happening in most browsers.
Managed to fix this for all browsers except IE 9
I put this bit of code into the bootstrap-table.js file at roughly line 1904.
var colWidth = $('#table thead')[0].children[0].children[index].children[1].getBoundingClientRect().width;
and changed line 1905/6 from
that.$header_.find(sprintf('th[data-field="%s"]', visibleFields[index]))
.find('.fht-cell').width($this.innerWidth());
to
that.$header_.find(sprintf('th[data-field="%s"]', visibleFields[index]))
.find('.fht-cell').width(colWidth);
We don't use anything below IE 9 and seems to work in 10 11 and edge.
you may need to clear the browsers cache to see the changes.
Any help with IE 9 would be appreciated.
As you can see here this is solved in our latest release http://jsfiddle.net/djhvscf/hf50xg7z/7/
