I use external buttons to trigger hardcoded filters/searches on click like these two:
Button one triggers
table.column(14).search('1').draw();
Button two triggers
table.column(15).search('1').draw();
This is working fine. As I understand it, the two searches could be chained like this:
table.column(14).search('1').column(15).search('1').draw();
This would perform the two searches in sequence, first in column 14 and then in column 15, the result being all rows with a 1 in column 14 AND in column 15.
Is there a way to write such a filter for the same content in the cells in either column 14 OR column 15?
