When editing the cell, data editor is created with old edited value (e.g. from different cell) then the value is updated to right value (second render)

[LiborOl]

It is caused by

 <DataCell ...
   editValue={this.state.editValue}

in DataSheet.

The data editor is rendered first time with value from previous edit and then the prop is updated with the correct value. It is not visible for the user, but if you use custom data editors, it may cause exceptions/warning because of different data types/structures.

I think, it is also source of the issue #218. All DataCells get the editValue.
