To know whether the background and border of empty cells are hidden in JavaScript, use the emptyCells property.
Example
You can try to run the following code to set whether to show the border and background of empty cells or not with JavaScript −
<!DOCTYPE html>
<html>
<head>
<style>
table, td {
border:1px solid;
}
</style>
</head>
<body>
<table id="myID" style="empty-cells:hide;">
<tr>
<td>One</td>
<td>111</td>
</tr>
<tr>
<td>Two</td>
<td>222</td>
</tr>
<tr>
<td>Three</td>
<td></td>
</tr>
</table>
<br>
<button type="button" onclick="display()">Return</button>
<script>
function display() {
document.write(document.getElementById("myID").style.emptyCells);
}
</script>
</body>
</html>
