Like Excel for the web, a bar in the upper part of the column-header strip and one in the left part of the row-header strip sit on the frozen panes' edges (the corner's edges when nothing is frozen). Dragging one previews the line and, on release, freezes up to the nearest column or row boundary through view.freezePanes; dragging back to the corner unfreezes.
