In the above example, multiple columns are modified, separated by semi-colons (;).
Each column setting is separated by the hat symbol (^).
[Ex103 should show that multiple settings for nameLens is allowed]
We also hide the CategoryID and Picture columns by using the gridLens property.
Only columns we want to display are listed here.
$lens->gridLens = "CategoryName;Description";
You can also change a column title dynamicly by clicking on the [pict here] button and
renaming the column: [picture here]
