I just updated my Datatable library from 1.10.12 to 1.11.4.
I use datatables extensively in my web app and after this upgrade I keep getting this error: https://datatables.net/manual/tech-notes/4 
I understand that this warning basically wants me to set a "defaultContent": "" to my column definition.
The problem is that I would need to update over 200 tables in the webapp to fix the issue.
Is there a way to set this defaultContent:'' globally ?
I have attempted a few things, but the most recent was to extend the defaults in datatables.js with this code
$.extend(true, $.fn.dataTable.defaults, {
columnDefs: [
{
targets:'_all',
defaultContent: "",
},
]
});
The problem with that, I think, is that in my tables I do this:
let columnCount = 0
let table = $("#someTable").DataTable({
data: [],
paging: false,
responsive: true,
sDom: '<"top"B>rt<"bottom"i><"clear">',
columnDefs: [
{
// Order
render: function (data, type, row) {
return row.sortOrder // If this is null or undefined that error shows up
},
targets: columnCount++
defaultContent: '' // I DO NOT want to add this to every single column in every table.
}
],
});
Which overrides the previous definition of the columnDefs.
Similar to this post: datatables default render function for empty cells
So going back to what I am trying to accomplish:
Is there a way to set this defaultContent:'' globally once and have it applied to all columnDefs?
One solution would be to change:
let columnCount = 0
let table = $("#someTable").DataTable({
data: [],
paging: false,
responsive: true,
sDom: '<"top"B>rt<"bottom"i><"clear">',
columnDefs: [
{
// Order
render: function (data, type, row) {
return row.sortOrder // If this is null or undefined that error shows up
},
targets: columnCount++
defaultContent: '' // I DO NOT want to add this to every single column in every table.
}
],
});
to
let columnCount = 0
let table = $("#someTable").DataTable({
data: [],
paging: false,
responsive: true,
sDom: '<"top"B>rt<"bottom"i><"clear">',
columns: [ <----- NOTE THIS CHANGE and no defaultContent
{
// Order
render: function (data, type, row) {
return row.sortOrder
},
targets: columnCount++
}
],
});
and have
$.extend(true, $.fn.dataTable.defaults, {
columnDefs: [
{
targets:'_all',
defaultContent: "",
},
]
});
This would still involve changing part of the datatables but not every single column definition at least.
