Metoda tabulky createTHead().

❮ Objekt tabulky

Příklad

Vytvořte prvek <thead> (a vložte do něj prvky <tr> a <td>):

// Find a <table> element with id="myTable":
var table = document.getElementById("myTable");

// Create an empty <thead> element and add it to the table:
var header = table.createTHead();

// Create an empty <tr> element and add it to the first position of <thead>:
var row = header.insertRow(0);    

// Insert a new cell (<td>) at the first position of the "new" <tr> element:
var cell = row.insertCell(0);

// Add some bold text in the new cell:
cell.innerHTML = "<b>This is a table header</b>";

Definice a použití

Metoda createTHead() vytvoří prázdný prvek <thead> a přidá jej do tabulky.

Poznámka: Pokud prvek <thead> již v tabulce existuje, metoda createTHead() vrátí existující prvek a nevytvoří nový.

Poznámka: Element <thead> musí mít uvnitř jeden nebo více tagů <tr>.

Tip: Chcete-li odstranit prvek <thead> z tabulky, použijte metodu deleteTHead() .
