columnDefs.targets

Assign a column definition to one or more columns.

1.10 The `dt-init columnDefs` option allows a column definition object to be defined and then assigned to one or more columns in a DataTable, regardless of the order of the column definitions array, or the order of the columns in the table. This `dt-init columnDefs.targets` option provides the information required by DataTables for which columns in the table the column definition object should be applied. It can be: * 0 or a positive integer - column index counting from the left * A negative integer - column index counting from the right * A string - class name will be matched on the TH for the column (without a leading `.`) * The string "_all" - all columns (i.e. assign a default) Additionally, `targets` can be either a single option from the list above, or an array of options (the different types can be mixed in the array if required). For example `targets: [ -1, -2 ]` would target the last and second last columns in the table. Please note that unlike all other column configuration options which can be applied to be `dt-init columns` and `dt-init columnDefs`, the `dt-init columnDefs.targets` option can only be used in `dt-init columnDefs`. columnDefs column() columns()
