Formatting data at cell level

Is there a attribute for the cell tag for the xml(the one that treegrid loads) for Formatting the data.

I know there is a method mygrid.setNumberFormat(…)

But i want to format data at cell levelIs that possible.

Formating can be applied only on column basis ( same format for all column ) , there is possible to mix formated and not formated cells in same column by using “per cell typing” ( “type” attribute of cell tag allows to set used excell type, so part of cells can be ed and part edn for example ) , but there is no possibility to have few different formats in same column.
