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

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