Expected behavior "searchValue" props in component as column can be number in MDBDatable.

Actual behavior MDBDatable crash after typing in search field. "TypeError: stringValue.toLowerCase is not a function"

Resources (screenshots, code snippets etc.) Problematic code fragment (filterRows function):

 if (sortRows && typeof row[key] !== 'string') {
    stringValue = row[key].props.searchValue;
 } else {
    if (row[key]) {
        stringValue = row[key].toString();
    }
}
if (stringValue.toLowerCase().includes(search.toLowerCase())) return true;

Is this a bug or intentional? There is no information about searchValue in the documentation or changelog. I found only one thread about it.
