CheckboxColumn extends DataSpreadsheetColumn

Boolean column for DataSpreadsheet. Renders a checkbox reflecting the value; activating the cell (click / Enter / type) toggles it inline instead of opening a floating editor.

Instance Properties


inputOptions

Extra Input.create options merged into every editor (override per type, e.g. number dump).

pasteAccepts

MIME types this column accepts on paste.

Instance Methods


cellAt()

A CellHandle for this column at a 0-based row index (or null).


cellHandles()

CellHandles for this column across the whole dataset (lazy, transient).


clear()

input(record, options)
    
    
    
        →
        
            
                
                    HTMLElement
                    |
                
                    null

Build the bound edit control for a record (mirrors Spreadsheet via Input.create). The returned element is two-way bound to record[attribute] — edits write back on change/blur — and is shown in a Floater over the cell. Returns null when the column isn't editable.
