Property	Type	Description	Default
cellEdit	boolean	Enables (disables) cell editing. When this option is set to true, Multi-select is disabled, onSelectRow can not be used, and hovering is disabled (when mouseover on the rows).	true
cellsubmit	string	Determines where the contents of the cell are saved: 'remote' or 'clientArray'. If 'remote' the content is immediately saved to the server using the cellurl property, via ajax. The rowid and the cell content are added to the url as name:value pairs. For example, if we save the cell named mycell,{id: rowid, mycell: cellvalue} is added to the url. If 'clientArray', no ajax request is made and the content of the changed cell can be obtained via the method getChangedCells	'remote'
cellurl	string	the url where the cell is to be saved	null

We can use all the available options in colModel that are used for inline and form editing, including clientSide validation e.g., editrules:{number:true...}
