Anybody knows how to make checkboxes selected by default? [rowIdentity]="rowIdentity" [displayCheck]="displayCheck" [selected]="selected" [selectionType]="SelectionType.checkbox" [selectAllRowsOnPage]="false" (select)="onSelect($event)"

in

Where "selected" corresponds to a list of objects

then in your component you will have these 2 actions

rowIdentity = (row: any) => {
    return row.id;
}

then you must specify what will be the identity column of each row with row identity

don't forget to declare it in : [rowIdentity]="rowIdentity"

The key is that you will have 2 lists: one for selected and one that corresponds to the data table. Then the objects you want to appear selected should be inserted in the selected list. In this way the library detects based on the selected list which should be marked by default in the table all this thanks to rowIdentity

If you want to add a select all must add an extra column with the following properties

<ngx-datatable-column
[headerCheckboxable] = true
[checkboxable] = "true"
>
</  ngx-datatable-column>
