[quote]

var oTable = $('#xStockDataTable');
FixedColumns(oTable, {
"iLeftColumns": 0,
"iLeftWidth": 15,
"iRightColumns": 6,
"iRightWidth": 929
});

0x800a01b6 - Microsoft JScript runtime error: Object doesn't support property or method 'fnSettings'
and dont show 4 another column.

please help me and thanks for your attention.

Currently no - this isn't possible. The number of fixed columns in FixedColumns cannot be dynamically changed. Sorry.
