There might still be a bug when the metakey is used for column sorting. I'll verify this later today or tomorrow. |

Defect Fixes
Fix #2979: Datatable performance improved by taking out parameters and functions of the BodyCells and placing in the BodyRow or TableBody components. Also, the set of BodyCell props to be checked when deciding for a re-render in React.memo was improved. This avoids now a lot of unnecessary re-render, including the issue from the linked issue.
Note that I also created a function called "selectiveCompare" in the BodyCell component to make the selection of which props should be checked at the React.memo. Maybe it makes sense to move it to the Utils, since it potentially can be used for optimizing the datatable further and more generally other library components. This selective comparison of the props is important since React.memo will not work as expected mainly if there are objects being parsed in the props.
