public void setAutoHeaderRefreshDisabled(boolean disabled) {
        this.headerRefreshDisabled = disabled;
    }
Enable or disable auto header refresh when row data is changed. By default,
headers are refreshed every time the row data changes in case the footers
depend on the current row data. If the footers do not depend on the current
row data, you can disable this feature to improve performance.

<p>
Note that footers will still refresh when columns are added or removed,
regardless of whether or not this feature is enabled.
