Hide

The simplest way to hide columns is setting column count property to the smaller number than actual number of fields in the dataset

var myCells = [
    ["Some text", "123", "456.00"]
];
...
obj.setColumnCount(2);

In addition it is possible to specify exactly which columns should be rendered by providing an array of column indices.

obj.setColumnIndices([1,2,3]); // column 0 is hidden
obj.setColumnCount(3);
