Is possible to translate columns title?

Is there a way to translate title strings from table headers ?

I’m using tap-i18n, I have also tried to call a function like:

tap = function (str) {
    return (Meteor.isClient) ? TAPi18n.__(str)  : " ";
}
... and then use
{ data: "someField", title: tap('name') }

but nothing is translated, it returns “name”.

Thanks

See #115 Recent versions of aldeed:tabular / datatables allow to specify a function for setting the column titles.

import {TAPi18n} from 'meteor/tap:i18n';

TabularTables = {};
TabularTables.Departments= new Tabular.Table({
  name: 'Departments',
  collection: Departments,
 responsive: true,
 autoWidth: true,
 stateSave: false,
 columns: [
    {data: "name", titleFn: function() {
      return TAPi18n.__("name");
    }},
    {data: "description", titleFn: function() {
      return TAPi18n.__("description");
    }}
  ]
});

The language change is reactive. If you have translations you can switch and columns will be translated.

TAPi18n.setLanguage("en");
TAPi18n.setLanguage("de");

Word of warning: This currently does not work when you include invisible columns in your table data. The offset is wrong and you get wrong column titles.

It’s ok if using

Template.<name>.rendered = function () {
     _.each($('thead tr th'), function (o) {
           $(o).html(TAPi18n.__($(o).html()));
     });
}

and setting title of each column as the string you have defined inside i18n.

I haven’t found a direct method, without the need to use Template rendered callback.
