		<parameter type="boolean" name="redrawCalculations" default="true">
			Indicate if DataTables should recalculate the column layout (`true` - default) or not (`false`). Typically this would be left as the default value, but it can be useful to disable when using the method in a loop - so the calculations are performed on every call as they can hamper performance.

	<description>
		Showing and hiding columns in a DataTable can be quite handy, particularly when showing tables with a large information density. This method allows the visibility of a single column to be changed on-the-fly, or the visibility state of a column to be read.

	<example title="Get the visiblity status of column index 0"><![CDATA[
var table = $('#example').DataTable();

alert( 'Column index 0 is '+
	(table.column( 0 ).visible() === true ? 'visible' : 'not visible')
);
]]></example>

	<example title="Hide the first column in the table"><![CDATA[
var table = $('#example').DataTable();

table.column( 0 ).visible( false );
]]></example>

	<example title="Hide multiple columns using `redrawCalculations` to improve performance"><![CDATA[
var table = $('#example').DataTable();

for ( var i=0 ; i<4 ; i++ ) {
	table.column( i ).visible( false, false );
}
table.columns.adjust().draw( false ); // adjust column sizing and redraw
]]></example>
