Fixed columns

It is possible to make the columns on the left or on the right side of the datagrid 'fixed' so they stay always visible during the horizontal scrolling. To make the column 'fixed' add fixed: true to the column configuration.

const columns = [
    { header: 'Company', template: 'company', fixed: true },
    // ...
];

You can make 'fixed' more than one column, both on the left and on the right side.
