How can I have multiple lines in my NSTextFieldCell in my NSTableView? By this I mean have multiple lines of data:

Parts of the solution would involve telling the cell that the text can wrap, and telling the table that the row heights vary. Getting the details right seems to be a tricky problem, or at least it was in 2005 when this discussion was written.

I know this question has been asked multiple times and were already answered using workarounds multiple times also. But just in case this 2021, someone might have a better solution for this.
What I have tried so far:
Background Image - It's hard(impossible) to align the contents perfectly.
Adding additional table rows and show/hide them based on row count. - Sometimes a row content could occupy more than 1 rows, thus generating an extra page.
This is my desired output.
But then, this inevitably happens:
Any suggestions, workarounds, opinions are gladly accepted. If ever an official solution exists, much better. Thanks.
Add additional logic to your hidden logic to account for the extra space in the Remarks.
This will add additional rows for every 60 characters:
CountRows() + SUM(INT(LEN(Fields.Remarks.Value) / 60))
You may have to play with the 60 number - it's just a guesstimate based on the remarks in your example. It won't be perfect since two text lines don't quite make up a single row but it should be close.
I've got a bit of a challenge with an HTML table that we need to have raised columns. If you look at the attached image you'll see what I mean.
The purpose of these raised columns is to draw the user's attention to them.
The problem is:
To get the effect of the column raising above the other columns you
need some kind of element/height/margin to appear outside the
boundary of the table, which doesn't seem to work
Same goes for the bottom
To have the drop shadow appear correctly, it needs to be applied to all the cells in a column.
We did get this to work by splitting it up into multiple tables then applying the styles to the table that should be the raised column. The image I've attached is actually a live table working like this.
But, you loose all other needed features of tables...
Row heights don't match if the text wraps in table 1 but not in
table 2.
To deal with the row height issue we applied a fixed height to each table's rows, but then you have to force text to not wrap. If you then get text that's longer than the width you run into trouble.
Does anyone know how this can be achieved without splitting the tables?
Thanks,

Try having an extra row for the table above the header row (you may have to stop using any th tags) to give you the overbar at the top. Similarly for the bottom, an extra highlighting row.
Although you have to compromise the table a little to do that, it is better in my book than separating into 2 tables, as that defeats all the purposes of the table tag; to show a table, and have that table easily declared.
The effects inside the table are probably best done with jquery, unless the choice of highlighted columns is entirely static, in which case consider rendering a static html version by generating the html appropriately.
I have an HTML table that can be more than 1K rows and a dozen or so columns.
I want the columns to be a fixed size (controllable by the user) and not grow/shrink either vertically or horizontally. So visually the contents of a particular table cell will be on one line and the overflow gets cut off at the end of the cell.
Doing performance analysis in Chrome on a large table the main performance killer is overflow:hidden.
I've tried putting the contents of each cell inside of an input, since that would replicate the same visual behavior, but that has a similar performance impact.
What do people recommend to improve performance?
If necessary I don't have to use a table tag, but would prefer to stick with the table tag if good performance can be achieved.
Update 1: I've included a file that demonstrates the performance issue here. Warning the file is pretty massive (25MB) and will slow down your computer. By default the table does not have overflow set to hidden, and once the table has been loaded (can take a while) the browser performance relatively smoothly.
However, if you edit the file and uncomment lines 12-15 and then open it. You'll see after loading browser around the table is significantly less responsive.
FYI: I have run into this problem on the iPad/iOS causing performance problems with a page that has about a hundred rows in a table with table-layout:fixed.
As soon as a cell, or a div in a cell, gets an attribute that forces it the cell to be drawn individually, it takes about 300ms instead of 100ms to draw (which causes the UI to feel abysmally slow for my situation).
Either of two properties (position:relative or overflow:hidden) caused the problem for me, removing them optimised the speed but caused text overflow if cell text was too wide for the fixed width columns.
The slowdown was happening even after tables were drawn, because I am dynamically popping up an absolute div over the table. When profiling the javascript (using (new Date).getTime()), the slowdown in measured in places in the javascript that have nothing to do with the table.
[edit: added following as part solution]
Put all cell content inside a span element (so can measure offsetWidth of content rather than width of containing block element).
After appending the row into the document, test if each span.offsetWidth is greater than the column width, if so add the "overflow:hidden" to the style (or via a class) of the containing block.
Can skip 1 and 2 above for some columns (if it is known that the cell content will never need clipping).
Caveats:
Measurements only made for iOS5 Safari (I didn't profile any other browser).
Works for us because we dynamically create table rows (processing your example using javascript would be slow?).
Most cells for our data do not overflow (clipping is only required sparsely - only a limited number of cells).
Compromised initial page load (generation of table in page went from 80ms to 800ms).
But sped up dynamic combo popup (340ms down to 130ms) giving much better keyboard responsiveness.
For your situation, might be fast to first using variable width columns, measure offsetWidth of all columns, setting column widths to pixel widths and setting overflow:hidden only on columns where offsetWidth of column is greater than the pixel width you will be using for the column.
You could try using a tiled approach. It is a pretty typical approach to making things like infinitely side-scrollable games efficiently.
Put all of your data into a Javascript array, and then have N + 1 rows in a table that has N rows visible. When you scroll down, the last item would move into view. At the moment that you have scrolled far enough that the first item moves out of view, you shift all of the data up a row and reset the scroll position back to where it started. Done correctly, the shift would be completely transparent to the user. You would only ever be working with N + 1 rows in an N-rows-visible table.
I've done this before, but under very specific UI constraints. I kind of shutter at the thought of making this consistent using the built-in browser scrollbars and such.
first off, the amount of markup required to have a table is much larger than just using divs with clear:both css for a new row. so that's the first performance hit.
also, you are setting the overflow as a class ( ? )
<style type="text/css"> .ovfl { overflow:hidden; }</style>
<td class="ovfl"></td>
As an aside, 1000 rows is a weight to deliver.
With divs you at least have an easier opportunity to throw those out of sight ( beyond the scroll ) into a div with display:none until the visitor scrolls to them.
few skins to cat mostly likely on this job,
Hope had some good thoughts.
Webkit bug 75001 is related to this problem and it covers the work being done to solve it (also see bugzilla dependencies for information).
I'm new on this particular project, and I've been tasked with resolving an issue that's appearing in IE8.
If you check http://funds.ft.com/ETFHomepage.aspx, There's a section called "News". In that section, there's a column called "Most Popular ETFs". This should be the same width as the "Recently Viewed ETFs" column.
For reference, this page is appearing correctly in Firefox. Can somebody please point out what I can do with CSS or (some other means)* to resolve this?
*I know the best way to resolve this issue is to scrap the terrible design and implement it correctly!! :-) -- we're actually doing that right now. It's a big job, so it's taking a long time. In the mean time however, we have to fix the bugs as they appear. Thanks
Update: just to note what I've said to Hristo, "I think the problem is with the table (rather, nested tables) on the left. The table in the center has its width defined by the image, and the table on the right doesn't have an image so it gets crushed"
Well the reason this is happening is because of the url you have under the "Alphaville: Overcoming the Volcker rule, with ETFs" header. Since the url has no whitespace in it, the table tries to give it space. So there are a couple of ways to fix this problem:
Plain text urls aren't very becoming on a webpage (especially when they're not in anchor tags so you can click on them.) Could you update the content so that you don't have a raw url in your content?
If you must be able to handle long lines of text with no whitespace then you need to figure out how to change the layout of the page so it forces the text to either wrap or clip to fit the container. Try playing around with putting "table-layout: fixed" on your tables to force the column widths to be sized based on the table's specifications only (instead of content). Firefox seems to be wrapping on dashes and slashes in the url whereas IE only wants to wrap on the dashes in the url.
I would say your layout is fine, and you just need to fix the content generation so it doesn't include any long plain text urls (option 1 above)
EDIT: If you do decide to go with option 2 above, then look into the css rule "word-break: break-all". It is IE only and it forces the text to break as soon as it reaches the end of the container. Not good for words, but it works for url's. So you couldn't apply this to the whole news table, but you could to just the cell that contains the url.
I have a report in SQL Server Reporting Services 2005. It makes use of a page header and footer and has no subreports. The body portion contains a few smaller elements and then a simple single column table. The table has a single header row and a single detail row. The header is just a label, basically. The detail row is a single textbox with a simple Fields!FieldName.Value as its output.
The problem is that FieldName, in this case, is a highly variable length string. It can be a sentence up to 8000 characters (usually no more than 2 pages worth). The text can contain line/paragraph breaks (returns) but no other special formatting. Everything is fine so long as the content fits on one page. Once the text exceeds a single page (8.5x11), the text is very nastily cut off abruptly. Since this is a pagination problem, it is only visible when exporting to PDF or when viewing the report in Print Layout.
It seems as though there is a maximum size the row can grow to on the first page and then it chops it off and starts it up on the second. But this cutoff is not carefully managed in relation to the text. It can occur right in the middle of a line, causing it to show the top halves of the letters on the first page and the bottom halves at the top of the second page.
Obviously, this is unacceptable, as it looks very unprofessional and can impair the readability of the line that was so messily split. I also can never be sure it'll split badly, as sometimes it more or less ends the page evenly, though usually I can still see the hanging tails of certain letters on the next page (g and p for instance).
The secondary problem is that I'd really like the table row header to repeat on each page. Setting the obvious property, "RepeatOnNewPage" has no effect. I suspect this is because it's still trying to show the single really vertically tall row. It seems like it's okay repeating headers and splitting pages nicely between detail rows. But because this is basically just a big block of text, and thus just one really tall row, it doesn't split it nicely.
What can I do or use to solve this problem? I can live without the repeating header so long as it just doesn't cut off text in the middle of a line.
Unfortunately, page break fine tuning is one of the biggest weak points of SSRS.
I can only suggest that you break up the long text into multiple rows before SSRS ever gets it. You'd want to parse the text to look for word breaks. The result will be odd looking breaks in the output since you won't know where the break will come on a line in the printed report. However, it'd be much more readable than cutting text in half.
If the text is comprised of reasonably sized paragraphs, you could parse it out that way instead.
You might even go so far as to measure the text using SQLCLR and the System.Drawing.Graphics.MeasureString method to fine tune the output but I wouldn't recommend that route for the feint of heart.
In SSRS 2008 R2 and Visual Studio 2008:
Click (not-right click) a textbox and go to the properties window (lower right side of VS) -> KeepTogether = false.
The text will cleanly cut between a line and continue on the next page.
Just thought to add here as searching for this doesn't return many results.
I have done what JC has suggested in the past where I've broken down the text into paragraphs and each paragraph would in effect be its own row. Works pretty well given the limitations of SSRS.
One thing to be careful about is that you would need to make sure that your paragraphs sort properly. In most cases it would display them in the correct order, but adding in a column with sortID to give some sorting hints to the table would probably be a good idea.
In the end, the cut-off-text problem was due to non-standard padding on the textbox in question.
For whatever reason, having padding any greater than the defaults (2pt all around) seemed to cause its pagination to go sour. I imagine it is due to the algorithm not taking padding into consideration when deciding where to break the paragraph. With default padding, the line always ends cleanly and nicely on each page.
As a workaround (since I liked the extra white space the padding gave to the layout), I used a rectangle to achieve the border and made the textbox inside it smaller than the rectangle by about an eighth of an inch. This gave the box some inner padding while still apparently allowing the pagination to correctly determine when to break up lines.
Still, a lot of unnecessary headache.
