Row height matching algorithm to use

3.1.0 The algorithm to use. This can be one of (see below for full description): * `-string none` * `-string semiauto` * `-string auto` The `-string semiauto` algorithm is used. FixedColumns operates by cloning the cells from the original table and then inserting them into the document, positioned visually above the DataTable - thus allowing them to appear fixed. As the fixed columns are separate HTML tables from the main table the row heights for the two must be matched - otherwise misalignment can occur. FixedColumns has three different algorithms that it can use: * `-string none` - will result in no height matching being applied by FixedColumns (height matching could be forced by CSS in this case) * `-string semiauto` - whereby the height calculation will be performed once, and the result cached to be used again * `-string auto` - height matching is performed on every draw (slowest but must accurate).
