I have a HTML table with several rows and columns and one radio-button in each column. I would like to make it possible to click in any row of the table to select the radiobutton in that column. I know it can be accomplished with the label-tag, by using javascript or some kind of CSS3.
But I would like to know if there is any pure HTML-way to do this? Without adding a label-tag for each cell in the table and not using javascript or CSS.
Because the table has like 15 rows and 10 columns, so it doesn't feel right to add 150 label-tags in the table and it would be nice not to have to rely on javascript or CSS3 that may not be supported or activated in all browsers.
I have read about the colgroup- and col-tags in HTML, but it doesn't seem they can add HTML like a label-tag for all cells in a column.
You should be able to add this feature with JavaScript. Add a click event to the whole <tr> in which you toggle the form field. I recommend using jQuery because it will (1) make this task a lost simpler, and (2) make your solution more likely to work across different browsers & versions.

I am trying to hide columns in a rhandsontable rendered in a Shiny app. I believe that in the current version it can't be done as explained here. However Handsontable does have a Hidden Columns plugin. I am not conversant with how to add plugins. If someone can show me, that would be great.
I am trying a css based approach but that's also failing. In my ui.R, I render the table using rHandsontableOutput("CargoListData"). This table CargoListData has 19 columns and I wish to hide the 18th column. It's a timestamp that I don't wish to display to the user, but I do need it in calculations when the user edits the table and saves it.
I have been trying to hide the column using some css code in my styles.css file of the Shiny app :
#CargoListData > * > td:nth-child(18) {
display: none;
}
However this has no effect on hiding the column. What am I doing wrong?
Since all else failed, here's something I discovered which handles this problem at least for now. My rhandsontable has 19 columns and I wish to hide the 17th to 19th columns. Specifying colWidths as 0.1 (and not 0) solves this.
hot_cols(colWidths = c(rep(150,16),rep(0.1,3)))
The Problem in Hand:
I want to make a form designer where user can drag and drop fields of different type and design the layout too, some what similar to wufoo form builder but here the layout is limited to single column whereas I want to make something where user can make the layout as they want.
I understand how to do in single column view, but could not understand how to achieve multiple column layout eg: row 1 there could be 3 elements, row 2 one element stretched to full length, row 3 there could be just 2 elements etc.
What I tried:
I have tried with jquery UI sortable to make a single column layout with using div where new elements can be dragged and repositioned.
Any suggestion on how to proceed further will be helpful
I have tried searching StackOverFlow and google but could not find any link on a similar topic. If anyone could point me to the same, it will be also helpful.
When you reorder elements on wufoo form builder, you can only drag'n'drop up or down. Remove that restriction and as soon as one element is dragged across a certain threshold, it "belongs" to the next column. If the "old" column was the first or last one and the line that the element was moved over was to the "outside" of the form, add a new column there, until the maximal number of columns is reached.
If the used drags the last element of a column into another column, remove the now empty column on element-drop.
You could also remove the dynamic adding/removing of columns and juist have a button ("remove column" & "add column") to do it by code.
An example for the dropping in another column can be found here: http://jqueryui.com/sortable/#connect-lists
Hope this helped!
Edit:
http://jqueryui.com/sortable/#portlets and http://jqueryui.com/sortable/#empty-lists also have elements that you could look into. Good luck! Sounds like a nice project. Can we see any progress or beta?
I am trying to create a Table that shall contain some columns with basic facts on the left and on the right side there shall be some columns that can be tabbed. Something like this:
So the Question is, how to do this?
I could personaly think of two solutions, but I actually don't like both:
Write a own Table for Tab1,Tab2 ... That contains the basic data and the Tabbed Data
Write a Table for the basic Data and one for each Tab. Here I think you would have a lot of Design problem "glueing" both tables together, so they look like one table.
So actually I don't like both solutions. Maybe there is a better solution to this?
Perhaps you could give the columns that belong to each tab their own unique class, e.g. .tab1-columns, .tab2-columns, etc. Then, you could show or hide the column depending on the active tab. The tabs, however, would exist outside of the table. Alternatively, you could pt the tabs into a pseudo- header row above the actual table header row, with the first header cell spanning those cells that shouldn't be "tabbed". However, I believe leaving the tabs outside of the table would be a bit more semantic in nature.
HTH.
Render all columns but hide them (display: none;) except the column by default.
Then add an click event on the tabs to switch the visible columns. be sure to use just the nav-tabs and not the js component.. it will be easier I think

I'm trying to make a table like this one where I have a profile image to the left, a bold title/name and text underneath the bold title/name, and date/time stamp underneath that... basically the same views as on that website (http://weknowwhatyouredoing.com/) or better (or twitter tweets).
Anybody know of any tutorials on how accomplish this? I'm currently using table with multiple columns but it seems that when one cell is big, all the cells in that row become the same height and i don't like that. In android this is called a list view but i'm not sure what it is in the html/css world, any help please? Thanks in advance
You could make multiple tables floating next to each other. The elements on the website you show aren't aligned as fa as I can tell.
A tutorial on rowspan and colspan can be found here.
If you make the image span 3 rows, you can put the bold text, content and date stamp each into one row. With valign you can vertically position elements within a row if the row becomes higher than the content. This will probably happen if the 3 rows together are higher than the one spanning row containing the image.
As a quick fix for your issue with the equal row heights, you could use the same layout method as they use on weknowwhatyouredoing.com.
Wrap each column in a separate <div>, and then place your <table> inside.
4 containers, 4 tables with independent row heights.
You shall give a look at the Twitter Bootstrap CSS library Twitter Bootstrap
It's pure HTML5/CSS using only divs.
for improve your knowleges in HTML, you can see W3C (Word Wibe Web Consortium) specs. For sample, if you see this page, W3C explain all structure, attributes, for Table element.
You can find lot of tutorial in google ( search "tutorial create Table HTML" ).
Also, you can help you to understand website structure with browser plugins that display hover element in specific website. ( firebug for Firefox and Chrome, Dragonfly for Opera browser...)
Why not use multiple list elements? Tables definitely don't give you flexibility for responsive designs. Making multiple columns of list elements can be rearranged as needed with limited restrictions
I've noticed a variation of convention when it comes to using DIV tags instead of TABLE to separate/organize content on a web-page. In what situation is one more appropriate to use than the other?
Clarification: This question is both general, and specific in that I'm mainly looking for which would be more ideal for page layout.
As a rule of thumb — if every cell in a row has something in common, and every cell in a column has something in common, then you should use a table. If you don't have a thead with some th elements providing column headings, then there is a good chance you are doing something wrong. If you don't have multiple data rows and multiple data columns, then … ditto.
The choice is, however, not between a div and a table. Use the markup that has the semantics that best describes the content. There are plenty of elements in HTML: http://www.w3.org/TR/html4/index/elements.html
Use tables only with semantically tabular data. Is each row other than the header representing the same "type" of "thing"? Does each column header have below it a set of items that are described accurately by the column header? If yes to both, then use a table. Avoid tables for styling whenever possible.
Table should be used to display tabelaric data ( like in excel for example) When Div tag is a container and should be used to organize content.
You can drive a nail with a screwdriver but proper tool is a hammer.
Simple.
Use a table for tabular data.
Use a div to separate content.
IMHO, a table is for the display of tabular data and related things, not for general layout of a page itself.
Some do not hold this purist opinion, and so use tables for laying things out because they seem easy to use.
Use div when you want to make your page more syntactically correct, use less bandwidth, make changes easily,make sites more accessible and more search engine friendly. In all other cases use tables (well except when you want to show some tabular data). Here are more details.
What I see a lot (and my biggest pet peeve), is people using a single column table to separate page elements or lists. Like:
<table>
<tr><td>
List item 1
</td></tr>
<tr><td>
List item 2
</td></tr>
</table>
instead of using
<li>, <p> or <div> (if its more like content)
The moral, its fine to use table where thy make sense- tabular data, etc. Never for lists, blocks. People complain about using it for layout, but sometimes it just works so that is the only place I make an allowance for abusing tables.
i use table only to display database fields and records.
i mainly use div for page layout.
Probably the only scenario where I'd use a table for layout over a div (other than for tabular data) is when creating HTML for an email. Emails clients aren't great at displaying HTML properly, so often using tables is the only way to get pages to display consistently.
It makes me die a little every time I have to do it :(
It does concern me that people are suggesting that table should be used for anything except tabular data, even in IE6. I think the only legitimate use of tables for non tabular data is in html emails, it's not the correct usage but the rendering in email clients is so awful you have little choice.
Semantics on your HTML have always been important, but I think it is only going to get more so especially with the new HTML5 tags that are being proposed... I can see more confusion over the use of article and section
Well, as far as I know, a table is used to organize a group of objects into set places ... say three pictures side by side all separated by some text.
And a is a "section" of a webiste. This can include anything, even tables!
So I guess the answer to your question would be: if you need to set up an organized array of images, text, etc. you might want to use a table (like an excel spreadsheet), but if you simply want to divide your website into sections, use tags.
By the way, as of late, tables are being used less and less and there seems to be a tendency to using different CSS layout techniques instead of tables.
Good luck!
