I am trying to minimize the height of the table shown below. Firebug
tells me that table's height is 29, tbody's 25, and both rows together's 23.
The layout tab does not show that there is any padding, margins or border.
Though, it tells me that tbody has 2 pixel offset, and the same for tr.
Is there a way to prevent that offset?
<body>
<table style="width: 100%">
<tr>
<td>foo
</td>
<td>bar
</td>
</tr>
<tr>
<td colspan=2></td>
</tr>
</table>
</body>

If I understood your question correctly, it looks like you want to do this on all your table elements:
padding:0px
border-collapse:collapse;

In general using a good reset.css should help you.
Maybe "CSS reset" will help:

I'm trying to create a table with a number of different sized cells, but from what I know creating tables with html/css seems too ridged for something like this:
Any help would be appreciated!
I think what you're looking for is cell width. You can do this in HTML (the CSS is only to show the result):
td {
background-color: red;
}
<table>
<tr><td width="500px">Cell 1</td><td width-"100px">Cell 2</td></tr>
</table>
You can change height too, but as far as I know you can only change height per row:
td {
background-color: red;
}
<table>
<tr><td width="500px" height="100px">Cell 1</td><td width="100px">Cell 2</td></tr>
</table>
in addition to the width and height of each , you can use the "colspan" and "rowspan" attributes as well. Like in the cell in your picture with the text: "Iraq war worth the cost", you can have something like the following:
<td rowspan="2">
See the following link for examples:
http://www.w3schools.com/tags/att_td_colspan.asp
I have a table with table-layout set to fixed. In the first row I have a td with text inside. It's something like:
<table>
<tbody>
<tr>
<td colspan="2" style=" min-width: 250px; width: 100%;">
<b>Vendor/Firm Information</b>
</td>
</tr>
<tr>
some content
</tr>
... and so on
</tbody>
</table>
So, the width of the first row is actually less than 250px. It's even less than content. So, I need to know: is there any reason for that? Is there something that don't allow the table cell to take appropriate width?
I use old version of Chrome (22.0.1229.0) and I think that it's rather a bug than incorrect styles.
In latest Chrome everything is alright.
I think that colspan="2" there is the reason.
There is no reasonable way to split that min-width between two spanned columns. So min-width constraint just get ignored on spanned cells.
Please see the response here:
Chrome, Safari ignoring max-width in table
The gist is that "max-width" only applies to block elements. So setting the table to "display: block;" should resolve the issue.
Ok, my problem is this, I had one master table and the <td>'s withing the table all aligned up pefectly and expanded nicley if header <th>'s wre beigger etc...
I had to break this table into 2 tables because I want the top portion to sort independent of the bottom section. Problem now is I have to manually set the width of the <td>'s in the bottom table so it has the same width as the top table. Is there a way for them to set automatically?
<table align="center" class="data_table" style="border-bottom-style: none; margin-bottom: 0px;">
<tr>
<th>
</th>
</tr>
</table>
<table align="center" class="data_table" style="border-top-style: none; margin-top: 0px;">
<tr>
<th colspan="9 title="Source of Repair (SOR) Remarks">SOR Remarks</th>
</tr>
<tr>
<td width="845px" colspan="9">
<textarea name="mcRemark" rows="7" cols="100" scrolling="auto">${mcRemark}</textarea>
</td>
</tr>
This
<td width="845px" colspan="9">
is the size of the top table and could change....thats my problem
They are now independent tables so the widths will be different.
You could use the data_table class to set the width of the cells in both tables to be the same.
Otherwise I'd imagine you could use javascript to grab th width of teh first table's cells and use those values to set the second table's cells. Bit messy though.
Without going with a javascript/jQuery solution, no, there is no way to do this with simple HTML/CSS. Rethink your solution by containing all data in one table, that way the TH's will dictate the column widths.
You could put them back in the same table and then pick a row to divide them and style that row to make it invisible. Through border colors and background colors. Faux two tables.
i have a table in my page, i use colgroups to format all cells in this column the same way, works good for background color and all. but cannot seem to figure out why text-align center does not work. it does not align the text centered.
example:
<table id="myTable" cellspacing="5">
<colgroup id="names"></colgroup>
<colgroup id="col20" class="datacol"></colgroup>
<colgroup id="col19" class="datacol"></colgroup>
<colgroup id="col18" class="datacol"></colgroup>
<thead>
<th> </th>
<th>20</th>
<th>19</th>
<th>18</th>
</thead>
<tbody>
<tr>
<td> </td>
<td> </td>
<td> </td>
<td> </td>
</tr>
</tbody>
</table>
CSS:
#names {
width: 200px;
}
#myTable .datacol {
text-align: center;
background-color: red;
}
Only a limited set of CSS properties applies to columns, and text-align isn't one of them.
See "The mystery of why only four properties apply to table columns" for a description of why this is the case.
In your simple example, the easiest way to fix it would be to add these rules:
#myTable tbody td { text-align: center }
#myTable tbody td:first-child { text-align: left }
That would center all table cells, except the first column. This doesn't work in IE6, but in IE6 the text-align does actually (wrongly) work on the column. I don't know if IE6 supports all properties, or just a larger subset.
Oh, and your HTML is invalid. <thead> misses a <tr>.
See similar question: Why is styling table columns not allowed?
You are only allowed to set border, background, width and visibility properties, due to the fact that cells aren't direct descendents of columns, only of rows.
There are a few solutions. The simplest is to add a class to each cell in the column. Unfortunately that means more HTML but shouldn't bee a problem if you're generating tables from a database etc.
Another solution for modern browsers (i.e. not IE6) is to use some pseudo classes. tr > td:first-child will select the first cell in a row. Opera, Safari, Chrome and Firefox 3.5 also support the :nth-child(n) selector so you can target specific columns.
You could also use td+td to select from the second column onwards (it actually means "select all td elements that have one td element to its left). td+td+td selects from the third column - you can continue in this fashion, overriding properties. Honestly though, it's not great code.
With the following CSS, you can just append one or more classes to the the table element in order to align its columns accordingly.
CSS
.col1-right td:nth-child(1) {text-align: right}
.col2-right td:nth-child(2) {text-align: right}
.col3-right td:nth-child(3) {text-align: right}
HTML
<table class="col2-right col3-right">
<tr>
<td>Column 1 will be left</td>
<td>Column 2 will be right</td>
<td>Column 2 will be right</td>
</tr>
</table>
Example: http://jsfiddle.net/HHZsw/
In addition to the limitations mentioned in other answers, as of February 2018, visibility:collapse still does not work on colgroups in Chrome and Chromium based browsers, due to a bug. See "CSS col visibility:collapse does not work on Chrome". So I believe the currently usable properties are just border, background, width (unless you employ some sort of polyfill for Chrome and other Chromium-based browsers). The bug can be tracked at https://crbug.com/174167 .
I have an empty table row just for separation between rows.
<tr>
<td colspan="5"></td>
</tr>
It's rendered in IE, FF, Opera and Safari. The question is, whether I should put some content inside of it or it is okay to leave it as it is?
Like:
<tr>
<td colspan="5"> </td>
</tr>
Well you could put an as column content to make sure the rows are displayed. The better way is to use CSS for spacing though.
Semantically, does the empty row serve a purpose, or is it purely for layout? If the latter, it may be worth considering dropping the empty row, and providing the separation via CSS. E.g.
<tr class="separate-below">
<td>Data before separater</td><td>More Data</td>...
</tr>
<tr>
<td>Data after separater</td><td>More Data</td>...
</tr>
With the following in the stylesheet:
TR.separate-below TD,TR.separate-below TH {
border-bottom: 1em solid white; /* use the background colour of a cell here */
}
Alternatively, you can use multiple <tbody> elements to group blocks of rows together (adding rules="groups" to the table element causes <tbody> elements to gain a horizontal border at top and bottom, and <colgroup> element to gain a border to their left and right):
<table rules="groups">
<thead>
<tr><th>Header</th><th>Header</th>...</tr>
</thead>
<tbody>
<tr><td>Data</td><td>Data</td>...</tr>
<tr><td>Data</td><td>Data</td>...</tr>
...
</tbody>
<tbody>
<tr><td>Data</td><td>Data</td>...</tr>
...
</tbody>
...
</table>
As you can see in this example from W3Schools using the is the best way to do what you want.
This is a very old question, but if somebody still needs a solution (problem exists with display: table-cell or table-row elements)
here's the solution:
.emptyElement:after{
content: "\00a0";
}
I wanted to add my solution which is a modification of #Dariusz Sikorski solution.
td:empty:after, th:empty:after {
content: "\00a0";
}
if you want to put content inside, i would use a no-breaking-space: , rather than a normal blank
You may have already tried this but if your trying to add some space in between rows have you tried adding some padding.
CELLSPACING=Length (spacing between cells)
CELLPADDING=Length (spacing within cells)

To ensure that empty cells are displayed the following CSS can be used:
table { empty-cells:show; }
You can use multiple tbody tags to group table rows. It's totally valid and more semantic.
