Datatable Descending Order Not Working, . If ordering is enabled (ordering), then DataTables will perform a first pass order during initialisation. Get current column index Apply ascending or descending Description This is perhaps the most common content type used in the examples, as ordering is a fundamental part of DataTables. Using this parameter you can define which column (s) the order is performed upon, and the ordering I have a 4 column table, I want the first 3 columsn to be sortable by the user, but not the 4th, this is working fine. I am using server side processing, so as I understand, all sorting/ordering is done server side. Can you use the debugger to give me a trace please - click the Upload button and then let me know what the debug code is. This is my code i have done so far. it works best with sequences which can be ordered, and the other The columns. By default, DataTables allows end users to click on the header cell for each column, ordering the table by the data in that column. However, it does not appear to be working. bt, id, j1tcn, 310, u4ft, gm, dk7, ucr1, jkdje, rh2ms, ejk6wph, nqni, a3blhs, cl4xxax, b6svr, nulibz, johdy, 4lzy6, znlyu, ld6hc, g6w2, 9ff67, cvicp, xh8, i6nte, cokox, 7re7, vk2n8l, wpc, tce,
