Situation: I have a complex setup with 7 DataTables generated through PHP and HTML directly on the page. Each summary level DataTable contains 6 nested detail level DataTables, except for one. Utilizing the responsive option, I'm able to display the content of the detail tables in a child row structure like demonstrated at https://datatables.net/examples/api/row_details.html
Challenge: My issue arises when trying to initialize each child table within the initComplete: function(){} of the parent table. While it does seem to trigger some action, the child tables lose the functionality typically associated with the DataTables libraries (such as column widths defined via columnDefs).
The primary concern is that my DataTable options, especially setting widths through columnDefs, are being ignored:
Is there something crucial that I'm overlooking? Why might the system be disregarding or overriding my column width specifications? The parent table supports both responsive and columnDefs.
Refer to the snippet below for an example scenario:
$('#summary_table').DataTable({
paging: false,
autoWidth: false,
searching: false,
columnDefs: [{
'width': '3%',
'targets': [0]
},
{
'width': '10%',
'targets': [1, 2]
},
{
"className": "dt-center",
"targets": "_all"
},
],
initComplete: function() {
console.log("Initialisation of table complete");
var sub_table = $('#summary_table').find('.ic-detail-table');
if (sub_table.length > 0) {
var sub_table_inst = $(sub_table).DataTable({
paging: false,
autoWidth: false,
searching: false,
columnDefs: [
//IGNORED????
{
'width': '10%',
'targets': [0]
},
{
'width': '25%',
'targets': [1]
},
{
'width': '25%',
'targets': [2]
},
{
'width': '40%',
'targets': [3]
},
{
"className": "dt-center",
"targets": "_all"
},
],
ordering: true,
sorting: true,
initComplete: function() {
console.log("SUB TABLE INIT COMPLETE");
},
responsive: true,
dom: '<"clear">rt',
order: [
[1, 'asc']
]
});
}
},
ordering: false,
responsive: true,
dom: '<"clear">rt',
order: [
[1, 'asc']
]
