Steps to Reproduce

run the attached example
6 columns 4~9 are rendered hidden (visible=false)

Current Result

the border between the cells in col-3 and col-10 is appears with 2px width

Expected Result

single pixel border between all columns

Debug Cause

the red border styles only highlight the problem it also happens without the borders, just not obvious

Root Cause

the "hidden" style of 0.1px adds up to 0.6px rounding up to a full pixel

Workaround

adjust the width to a smaller value making it less likely to cause double pixel borders e.g. 0.001px

	zk.afterLoad('zul.mesh', function() {
		var xMeshWidget = {};
		zk.override(zul.mesh.MeshWidget.prototype, xMeshWidget, {
			bind_ : function() {
				var result = xMeshWidget.bind_.apply(this, arguments);
				var adjustWidth = function() {
					if (this.style.width === '0.1px') {
						this.style.width = '0.001px';
					};
				}
				jq(this.ehdfaker).children().each(adjustWidth);
				jq(this.ebdfaker).children().each(adjustWidth);
				jq(this.eftfaker).children().each(adjustWidth);
				return result;
			}
		});//zk.override
	});//zk.afterLoad

the goal should be to evaluate whether this workaround of only fake hidden columns is still necessary, and apply it only to browsers needed
