How to ignore first <tr> in jquery.datatables?

Question

I have a table where the first <tr> I put an image, if when I search comes along the name of the image.

For example: in the first row of table a img is named after head.png and the rest of the line doesn’t have the letter p.

Only when I put to search "p" the search shows me the first line.

But when I put at least one line without img he can search.

You can control what is searched (and even what is ordered) through the option Columns.render.

In this case, a function should be passed and treated when second parameter type have the content filter. The fourth parameter meta can help determine which is the line without depending on any additional data in the table, because meta.row is the index of the line.

It would look something like this:

render: function (data, type, row, meta) {
    if (type == "filter" && meta.row == 0)
        return "Texto customizado"; //aqui fica a seu critério o valor que será pesquisado

    return data;
}

render: function (data, type) {
    if (type == "display")
        return data;
    else if (type == "filter")
        return "Texto customizado";
