This is my code:
<html>
<style>
.left-info
{
font-size:14px;
font-family:Tahoma, Helvetica, sans-serif;
color:#1A5B71;
font-weight:bold;
text-align:right;
}
.right-info
{
font-size:14px;
font-family:Tahoma, Helvetica, sans-serif;
color:#FFFFFF;
font-weight:bold;
text-align:left;
}
</style>
<body>
<table border="1">
<colgroup>
<col class="left-info" />
<col class="right-info" />
</colgroup>
<tr>
<td>3476896</td>
<td>My first HTML</td>
</tr>
<tr>
<td>5869207</td>
<td>My first CSS</td>
</tr>
</table>
</body>
</html>
But, it is showing simple table. Need help !!
Look here
http://www.w3.org/TR/CSS21/tables.html#columns
You can only set border
, background
, width
and visibility
with col
s
According to MDN, the only allowed attribute on <col>
is span
. All others are deprecated.
With this little jQuery snippet you can copy all the class names from the col
tags to the corresponding td
tags
It works even with colspan in both col
and td
tags as well as with nested tables.
JavaScript
$(document).ready(function() {
var find_TDs_at_COL = function(table, col) {
var ret = [];
$(table).children('tbody').children('tr').each(function() {
var col2 = 0;
$(this).children('td,th').each(function() {
oldCol2 = col2;
if ($(this).attr('colspan')) {
col2 += parseInt($(this).attr('colspan'));
} else {
col2++;
}
if (oldCol2 <= col && col2 > col) {
ret.push(this);
}
})
})
return $(ret);
}
$('table > colgroup').each(function() {
var $table = $(this).parent();
var col = 0;
$(this).children('col').each(function() {
var oldCol = col
if ($(this).attr('colspan')) {
col += parseInt($(this).attr('colspan'))
} else {
col++;
}
for (var i = oldCol; i < col; i++) {
find_TDs_at_COL($table, i).addClass($(this).attr('class'))
}
})
})
})
console.clear()
