subrow's height in datatable

My datatable has subrow made by dynamically html.
When the sub row has opened, the height of subrow is not working normally.

I found a solution.
When draws the suborw, give height of subrow to subrow’s object.
Like this,

subrow:function(obj) {
var html = ‘’;
for(var i=0, len=obj.id; i<len; i++) {
html += ‘

asdfasdfasdf
’;
}
obj.$subHeight = obj.id * 30;
return html;
},

webix text size calculator forces div to have inline style.
depending on your logic you can force them to have block style
html += '<div style="display:block!important">asdf</div>';
or use p element, or divide by br
