How to resize column width in report?

hi all,
i read somewhere here that in order to resize column width in a report, you need to go to report attributes, then edit the column you wish to resize and then go to the CSS Style and place something like "width=600px". while this works very well in Internet Explorer, it somehow has no effect in Firefox 3.0. is there a way to make it work both browsers?
thanks
allen

Hi,
Sorry, I misunderstood. There are several methods you could use:
1 - Use the span tags around the data itself - this would require adding the tags into the sql statement itself
2 - Use javascript to set the column widths by adding a style to the TD tags for each cell
3 - Create a new Report Template and use COL tags immediately after the TABLE tag in the Before Rows section to specify the widths of all columns
Option 3 may be the easiest?

Resizing columns and making multiple selections in Pages 5.0

Using Pages 5.0 (using OS X), I am no longer able to resize columns in a table by dragging a selection handle as I could in the old Pages (2009, I think it was). Dragging now adds the adjacent column to the selection. Anyone know how to resize the columns by dragging?
Also, in the previous Pages, I could select multiple noncontiguous words by holding down the command key. Doesn't work anymore. Does anyone know how to do that?

Apple has removed 90+ features from Pages5:

Pages '09 should still be in your Applications/iWork folder:

Trash/Archive Pages 5 after exporting any Pages 5 files back to Pages '09 format.
Then rate/review Pages 5 in the App Store.

Resize columns in Pages for iPad?

Is there a way to resize columns in a multi-column document in Pages for iPad? I want a narrow left column and a wider right column. I can kinda get the effect by using a table, but it'd be easier to just adjust the column widths. Is this possible, and if so, how?

Hi Adarga,
I'm not seeing a way to resize the columns and the Help doesn't mention it either. I'm just able to change the indents and "margins" within the columns, but the columns stay the same size.

Resizing columns in iTunes 10

I've noticed some strange behavior in iTunes 10 regarding the resizing of displayed columns in List view. It appears that I can resize any displayed column in my main library, with exception to the immovable 1st column (the "currently playing or paused" column) or the checkmark column. This is fine.
The problem comes when I try to resize columns on an attached iPod. I can resize some columns, but not all ... that makes no sense! For instance, with my current settings, the optional displayed list view columns for my iPod are (currently in this order):Artist, Track #, Time, Album, Date Added, Size, Kind, Bit Rate, and Rating. In addition to these, there are the 3 default columns: the song order/play status column, and the Name column. I can't resize any of the default columns, nor can I resize these columns: Date Added, Kind, Rating, or Size.
Also, you should be able to resize the columns in the Column Browser, but you can't do that in either the main library OR an iPod library.

While viewing your iPod Library, try opening View Options (on my Mac, it's Cmd-J). Uncheck the columns you can't resize, and click OK. Those columns should disappear. Open View Options again, and recheck them. See if you are now able to resize them. This procedure worked for me on iTunes 9.2.1.

Disable sorting and resizing columns on table view

Is there a way to disable sorting and resizing columns on table view?
Thanks

Use
setSortable(false)
setResizable(false)
on each TableColumn

Explain plan needs resize columns best-fit

Is there an easy way to resize columns in the explain plan grid? They are difficult to resize if the values in them are long, especially the access and filter columns at the end.

There is only one way to resize these right now (and thats the one you are using).

Can't resize column to fit text

Can't resize column to fit text in numbers. option is "grayed-out" no matter what I do

It is either a glitch or a rather unfun new thing. No one knows for sure. You do have a bit more control if you go into your photos app, find your photo and tap on the little box with the arrow poking out of it. That allows you to send it to be wallpaper. You can do some scaling, although not as much as you used to.
Finding work arounds is about all you can do until it's fixed.

JTable user resize columns with grid?

Is it possible to allow a user to resize columns not just through the table header, but with the vertical grid lines?

There is no method that allows you to toggle this
feature on/off if thats what you are asking.Yes, thats what I was asking.
If you want to implement this type of functionality
yourself then take a look at the source code for
JTableHeader to see how its done.Thanks, I'll look into that - though it would be cool if that was already a feature of JTable.

Resize column width for JTable without column headers?

Hi,
I find that for me to resize columns of a JTable by using
mouse dragging, I MUST have column headers and then drag
column headers to resize them. Is my understanding correct?
Actually, I need to have a table without header columns.
How can I use mouse to resize column width by dragging?
The background for this request is that I am putting a
complex table as another table's column header and I hope to
be able to resizing the complex table by mouse dragging.
Thanks very much,
David

Hi,
I think you have mistake there. Try
<style type="text/css">
table.apexir_WORKSHEET_DATA td {
white-space:nowrap !important;
td[headers="DESCR"] {
width:300px !important;
max-width:300px !important;
#apexir_DESCR {
width:10px;
max-width:300px !important;
</style>And you can try add
table.apexir_WORKSHEET_DATA {
width: 100% !important;
table-layout: fixed !important;
}Regards,
Jari

Resizing columns in iTunes store

Ok so they new look is bland, boring, and uncreative. But, I don't have a choice. Feels like I walked into a walmart store. But, whatever.
How do you resize columns in the iTunes store? I cant read the song names because apple has no resizing feature. And it's very annoying.
Thanks,
Nick

I completely agree - this is annoying! I found another topic in this forum about this where it was suggested that Apple be contacted via their feedback form at http://www.apple.com/feedback/itunesapp.html. I've just done this and suggest that anyone else who finds this annoying do the same! Hopefully, if more people report it, it will be fixed in the next update.
Another topic I came across suggested using the Browse feature (by going to the Home page, then clicking "Browse" in the top right quick links). This will return results in a list similar to the previous version, which had resizable columns. The only trouble is, you can't search this way, only browse, so it still doesn't assist in making locating tracks more efficient :S

Can't resize columns in new iTunes store

Well .. the new iTunes9 store is just horrendous, and a step back from the previous version. i'd beg for the previous version but it's never gonna happen.
one of the most simple and yet horrendously awful things is the apparant inabilityto resize columns when browsing an arists. if the name of a track is wider than the column ... how do you see it? there is now way to scroll across and see the complete name of the track/remix.
anyone know a work around for this. anyone from Apple care to comment on such an obvious design flaw?

I'll echo this. Look up Classical Music, anything there is nigh impossible to find. Telling me that a song is "symphony no. 9 movem...." is useless. I don't care, I know that. What I want to see is the movement. But I can't. Or how about dance remixes? I know the name of the song, I'd like to be able to see the actual remix name.
On top of that, you can't even choose what you want to view by. If I am searching for all the U2 songs, I don't need to see that the artist is U2. I'd much rather use that space for more productive things.
I simply cannot understand who at Apple thought this was a "better" user interface. Sacrificing user operability for a "spiffy" new makeover is not what I would expect from Apple.

Cannot resize columns in Coverflow in Finder

my mid 2009 MBP using ML will not let me resize columns in Finder when in coverflow view as i can when in list view. this is sort hard to manage and i'd like to fix it.
any ideas?
TIA

hi sb.
i may be mistaken here. i am trying to start working in ML on the laptop after getting things organized and maybe i am not understanding something.
does finder in ML open to some kind of "global" Finder Window that sometimes shows all files or is somehow different than the second finder window?
or - - er (testing here), i guess when you /first/ open Finder you see this bar that won't resize but if you actively then select something in the pane on the left or if you open a /second/ Finder window i don't see this image that doesn't have the ability to resize the columns...?
THANKS

Resize column width in ALV

How can we resize column width in WebDynpro ALV same as in SAPGUI?

Hi Khandal,
Thomas has said about the same resizable feature in this [thread|Adjusting Column width on Web Dynpro ALV;.
"That functionality is there in 7.0 Enhp1. It works for standard tables and ALV. You only have to set the fixedTableLayout property to True. Here is a video of it:

Broken: Copy & Resizable Columns

In iTunes store I used to be able to copy track information by selecting a track and typing cmd-C. This was useful for a number of reasons, the two most used by me were correcting ripped CD information quickly -- particularly with classical tracks where the titles and track names have no real quality control -- to make it match the iTunes database (that makes getting cover information much easier); and sending information to people (including Apple support) in emails.
Now I can't do that. This would be a minor inconvenience were it not for the disappearance of resizable columns. Before, a work around would be to open the CD information in a separate window, rearrange my windows so that I can see everything, and simply eyeball everything (I can touch type so while that's a hassle, it wasn't impossible).
Unfortunately, that doesn't work now either. The columns are fixed in width meaning many classical tracks have long titles that start with the same text (like Symphony No. 3 "Poem of Ecstasy" or "Concerto for Two Violins and Orchestra") that runs over into the non-visible part of the column. The only way to read the entirety of what's there is to hover the mouse over the visible text. This is impossible to do while typing in another window because it only works while the store window is active.
Thanks, Apple. You've opted for style over substance again, only this time it doesn't work.

Byron,
I think I have a better answer for you.
When you are on the Home screen of the iTunes Store click the Browse in the QuickLinks on the upper right of the screen.
You will then be switched into the conventional iTunes bowser where I think you'll find you can copy and paste track information as you have in the past.
Give it a try.

doLayout() method only can be used when table resizes. first off all i want to restrict table resizing with in the limited size
