Table rules Property
Table Object
Definition and Usage
The rules property sets or returns which inner-borders (between the cells) that should be displayed in a table.
Syntax
Set the rules property:
tableObject.rules="none|groups|rows|cols|all"
Return the rules property:
tableObject.rules
| Value | Description |
|---|---|
| none | No inner-borders are displayed |
| groups | Inner-borders are displayed between row groups and column groups |
| rows | Inner-borders are displayed between rows |
| cols | Inner-borders are displayed between columns |
| all | Inner-borders are displayed between rows and columns |
Browser Support
The rules property is supported in all major browsers.
Note: IE9 displays this property correctly. Earlier versions of IE adds the four outside borders in addition to the inside borders.
Note: Chrome and Safari displays this property incorrectly: They add the affected outside borders in addition to the inside borders.
Example
Example
Set two different inner-borders of a table:
<html>
<head>
<script>
function rows()
{
document.getElementById('myTable').rules="rows";
}
function cols()
{
document.getElementById('myTable').rules="cols";
}
</script>
</head>
<body>
<table id="myTable">
<tr>
<td>cell 1</td>
<td>cell 2</td>
</tr>
<tr>
<td>cell 3</td>
<td>cell 4</td>
</tr>
</table>
<br>
<button type="button" onclick="rows()">Show only row borders</button>
<button type="button" onclick="cols()">Show only col borders</button>
