Search

can have as many columns in the datatable field

true, 'ajax': { url: '/api/base/?format=datatables'}, 'columns': [ {'data': 'p_id_s'}, {'data': 'patientid.patientid'},

are data of the columns in the datatable. format:

table : var table = $("#listSauvegarde").DataTable({ columns: [ { data: 'id' }, { data: 'client_name'

Chrome and it seems to happen at 420px and below. Take a look at the resolution in 361px wide for example. The columns are supposed to collapse under the green buttons when there isn't enough room.

That's not what I'm looking for. What I need is that if my table has 2 columns, or if I have 3 or 4 columns, they cover the entire page, regardless of the width assigned in the table structure.

Try this for your column: columns: [ { data: "yourDateField", render: function ( data, type, row ) { return moment(data).format('DD/MMM/YYYY'); } }, The following isn't really used for rendering but to tell the ultimate date sorting plugin what the date format is: $.fn.dataTable.moment('DD/MMM/YYYY'); https://datatables.net/blog/2014-12-18

column().search() could be used to search for data in a specific column. If you need something more complex (i.e. conditionals over multiple columns) then a custom search function could be used. Allan

might move groups of columns, or a grouped item

default content for all columns in case of empty
