lastnosti rows,
in v vsaki vrstici pojdimo skozi njene celice z uporabo
lastnosti cells:
<table id="table">
<tr>
<td>1</td><td>2</td><td>3</td>

for (let row of table.rows) {
for (let cell of row.cells) {
console.log(cell);
}
}
Primer
Pojdimo skozi vse vrstice tabele z uporabo
lastnosti rows
in ugotovimo število celic v vsaki vrstici:
<table id="table">
<tr>
<td>1</td><td>2</td><td>3</td><td>4</td>
</tr>
<tr>
<td>1</td><td>2</td><td>3</td>
</tr>
<tr>
<td>1</td><td>2</td>
</tr>
</table>
let table = document.querySelector('#table');
for (let row of table.rows) {
console.log(row.cells.length);
}
Primer
Nastavimo ozadje prvi celici:
<table id="table">
<tr>
<td>1</td><td>2</td><td>3</td>
</tr>
<tr>
<td>4</td><td>5</td><td>6</td>
</tr>
<tr>
<td>7</td><td>8</td><td>9</td>

</table>
table, td {
border: 1px solid black;
}
let table = document.querySelector('#table');
table.rows[0].cells[0].style.background = 'red';
:
Primer
Nastavimo ozadje celicam tabele diagonalno:
<table id="table">
<tr>
<td>1</td><td>2</td><td>3</td>
</tr>
<tr>
<td>4</td><td>5</td><td>6</td>
</tr>
<tr>
<td>7</td><td>8</td><td>9</td>
</tr>
</table>
table, td {
border: 1px solid black;
}
let table = document.querySelector('#table');
let rows = table.rows;
for (let i = 0; i < rows.length; i++) {
rows[i].cells[i].style.background = 'red';
