Hi,
It seems there is an issue in datatable.hideColumn:
if (hindex >= this._hidden_split[1]) this._settings.rightSplit += span;else this._rightSplit += span;
When hindex >= this._hidden_split[1], rightSplit will be changed.
It will even create rightSplit for datatable with no rightSplit setting.
It seems the correct one should be
if (hindex >= this._hidden_split[1] && this._hidden_split[1]>0 ) …
Regards
Wicky
