I reported this last week but it got declined ?? Perhaps a picture will help
The default grid displays the filter icon OVER the text and this makes the text unreadable. This is just the material format from your websites themebuilder
The icon should be closer to the column width adjuster - as you can see from the attachment there is more space between the columns than there is text
I would expect it to be "| Description Y |" and not "| Desc... Y |" which is what its doing. (really the space between the filter icon and the column adjusted is just wasted and there seems to be no way to fix it)
I've tried to move the k-i-filter using CSS and while giving it a left margin of 32px is working ok and making it look reasonable, it still has the circle highlighter when you click it in the wrong place and I can't figure out how to move that also.
