### Remarks

Some of the fields in the MultiColumnHeader state are serializable so they can be preserved between assembly reloads and/or when restarting Unity. The non-serialized fields have to be reconstructed. After having reconstructed the state use this method before calling [MultiColumnHeaderState.OverwriteSerializedFields](/engine/6000.3/script-reference/unityeditor/imgui/controls/multicolumnheaderstate/overwriteserializedfields.md) to apply any serialized fields from a previous session.
