Hide empty cells in table

问题

I want to hide empty cells in table. Here is my code:

$(function() {
  $(".empty").each(hideCellIfEmpty);
});

function hideCellIfEmpty() {
  var theCell = $(this);
  if (theCell.html().length == 0) {
    hideSoft(theCell);
  }
}

function hideSoft(jQElement) {
  jqElement.css('visibility', 'hidden');
}

table.empty {
  width: 350px;
  border-collapse: collapse;
  empty-cells: hide;
}
td.empty {
  border-style: solid;
  border-width: 1px;
  border-color: blue;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<table class="empty">
  <tr>
    <th></th>
    <th>Title one</th>
    <th>Title two</th>
  </tr>
  <tr>
    <th>Row Title</th>
    <td class="empty">value</td>
    <td class="empty">value</td>
  </tr>
  <tr>
    <th>Row Title</th>
    <td class="empty">value</td>
    <td class="empty"></td>
  </tr>
</table>

You can see, empty cell is shown in 2nd row. But I want to hide it. Moreover, I don't want to use border-collapse:separate. Is this possible to hide the empty cell using border-collapse:collapse? I also want to know why this is showing empty cells.

P.S. Using border-collapse: separate is working and does not show empty cells.

$(function() {
  $(".empty").each(hideCellIfEmpty);
});

function hideCellIfEmpty() {
  var theCell = $(this);
  if (theCell.html().length == 0) {
    hideSoft(theCell);
  }
}

function hideSoft(jQElement) {
  jqElement.css('visibility', 'hidden');
}

table.empty {
  width: 350px;
  border-collapse: separate;
  empty-cells: hide;
}
td.empty {
  border-style: solid;
  border-width: 1px;
  border-color: blue;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<table class="empty">
  <tr>
    <th></th>
    <th>Title one</th>
    <th>Title two</th>
    <th>Title three</th>
  </tr>
  <tr>
    <th>Row Title</th>
    <td class="empty">value</td>
    <td class="empty">value</td>
    <td class="empty">value</td>
  </tr>
  <tr>
    <th>Row Title</th>
    <td class="empty">value</td>
    <td class="empty"></td>
    <td class="empty">value</td>
  </tr>
</table>

But this does not answer these questions:

Why empty-cells are displayed when border-collapse: collapse is used ?
Why empty cell are not displayed when border-collapse: separate is used ?

回答1:

If your site doesn't require support for IE 8 and under, you could just use the CSS :empty pseudo-class:

td:empty {
  visibility: hidden;
}

table.empty {
  width: 350px;
  border-collapse: collapse;
  empty-cells: hide;
}
td.empty {
  border-style: solid;
  border-width: 1px;
  border-color: blue;
}
td:empty {
  visibility: hidden;
}

<table class="empty">
  <tr>
    <th></th>
    <th>Title one</th>
    <th>Title two</th>
  </tr>
  <tr>
    <th>Row Title</th>
    <td class="empty">value</td>
    <td class="empty">value</td>
  </tr>
  <tr>
    <th>Row Title</th>
    <td class="empty">value</td>
    <td class="empty"></td>
  </tr>
</table>

More about the :empty pseudo-class can be found at https://developer.mozilla.org/en-US/docs/Web/CSS/:empty

Assuming all cell you want to hide have the class ´.empty()´ I came up with this piece of jQuery:

$(function(){
    $(".empty").each(hideCellIfEmpty);
});

function hideCellIfEmpty(){
    var theCell = $(this);
    if(theCell.html().length == 0){
        theCell.hide();
    }           
}

aaaaand... it seems to work. :)

However as hide() doesn't preserve space you run into this problem if you try to do a donut shape.
Luckily there is another question discussing this problematic and the answer is to use

css('visibility','hidden')

Witch you can also find in this fiddle.

I found this solution on a good article I was reading.

I hope it will work for you too:

table {
   empty-cells: hide;
}

Best regards!

Try the following

<style type="text/css">
table.empty{
    width:350px;
    border-collapse: collapse;
    empty-cells:hide;
}
td.normal{
    border-style:solid;
    border-width:1px;
    border-color: blue;
}   
td.empty{      
    style:'display=none'
}

</style>
<table >
<tr>
<th></th>
<th>Title one</th>
<th>Title two</th>
</tr>
<tr>
<th>Row Title</th>
<td class="normal">value</td>
<td class="normal">value</td>
</tr>
<tr>
<th>Row Title</th>
<td class="normal">value</td>
<td class="empty"></td>
</tr>
</table>

Just used CSS: empty-cells: hide;

Browser supported: Verified Link or Link 2

table { 
    border-collapse: separate;
    empty-cells: hide;
}

NB: You can't use border-collapse: collapse; because it make Disable look empty cell hide

/******Call-Padding**********/

table { 
  /***
  border-collapse: collapse; #Not use it     ***/
    border-collapse: separate;
    empty-cells: hide;
}

td { 
  border: 1px solid red;
  padding: 10px;
}

	<table>
		<tr>
			<th>Head1 </th>
			<th>Head2 </th>
			<th>Head3 </th>
			<th>Head4 </th>
		</tr>
		<tr>
			<td>11</td>
			<td>12</td>
			<td>13</td>
			<td>14</td>
		</tr>
		<tr>
			<td>15</td>
			<td>16</td>
			<td></td>
			<td>18</td>
		</tr>
		<tr> 
			<td>19</td>
			<td></td>
			<td>21</td>
			<td>22</td>
		</tr>
		<tr>
			<td></td>
			<td>24</td>
			<td>25</td>
			<td>26</td>
		</tr>
	</table>

Here's another sollution, since td:empty didn't work for me:

<style type="text/css">
    table {
        border-spacing: 0px; // removes spaces between empty cells
        border: 1px solid black;
    }
    tr, td {
        border-style: none; // see note below
        padding: 0px; // removes spaces between empty cells
        line-height: 2em; // give the text some space inside its cell
        height: 0px; // set the size of empty cells to 0
    }
</style>

The given code will completely remove any space an empty row would otherwise take up. Unfortunately you have to set border-style: none;, else the borders of empty cells will be painted anyway (which results in thick lines).
