Frozen columns

Frozen columns

Sometimes it is very convenient if part of table columns are always visible independently on position of horizontal scrolling. The Frozen columns mode allows to split table into two grids with independent horizontal scrollbar each.

The Frozen columns mode is compatible with paging, readonly columns, and Dynamic loading mode.

Code of the example
