The file Plugins / integration / bootstrap / 3 / dataTables.bootstrap.css has the following code (lines 42-47):
table.dataTable {
clear: both;
margin-top: 6px !important;
margin-bottom: 6px !important;
max-width: none !important;
}
Because of the 6px margins, when using option sScrollY with bootstrap3, there comes a visible space between the table header and body. Setting the margins to 0px instead of 6px fixes the issue.
