I need to create three divs, next to each other (attribute float:left).
Then I read the data from database and I need to present this data in three divs, in such a way that I first fill up the first div, line by line and when I reach certain height, I go to the next div and fill it with data, and so on.
This is something like reverse table, that is I first fill the first column in first row then go to second and so on until the end of the row, then I move to the second column of first row
and so on. I hope you get the picture.
Is there a way to achieve this in CSS or in some other way?
This functionality is available in CSS3 using column-count and column-span.
I do not know how to make it efficient, but it should be possible with javascript... you know the line-height, you check the height of first div with all content, then you truncate it to desired size and the rest put to the next div.. repeat.. but this looks odd.. ?
You might be able to do this by requesting the first 30 results in the database in one column, then request the next 30 in the next div, and so on. I can't see it being possible in CSS 2.1 alone.

I work with ssrs with a dynamic row data in matrix/tablix. There is possibility when I have more than one page (say it two pages) where the data just fill half of the second page and leave a blank space below (half page blank space on the second page). How is the way to fill this blank space with empty rows? (whether rendering empty rows in the tablix, or inserting background image, or anything. I don't have any solution yet as it is dynamic data with many possibilities of the blank space size on the page)
Unfortunately there aren't any settings in the reporter that support this behavior. There are however several workarounds you could use to get the wanted result.
[1]
You could determine the amount of rows that fit on the first page and on the second page, just in case you have items above the
table on the first page. Before you send the datasource to the
reporter count the total rows and check if it exceeds the first page.
Then calculate the number of rows missing to fill an entire second
page (or third/fourth... if you ever get more data). Finally you add
empty rows/objects at the end of your datasource, which will of cource
cause the pages to be filled to the end.
As was pointed out before, this solution is only possible when working
with fixed row heights. If certain columns can have multi-line cells
then these could be checked as well and taken in account when
calculating the number of rows being displayed on the page. This makes
it slightly more complicated but is still a valid solution if you can
predict which columns might be troublesome.
[2]
A second solution would be to hide the table borders and place the table inside a rectangle that spans the maximum size of the
page. The borders of this rectangle can be used to display the table
outer borders and columns can be displayed by adding lines inside the
rectangle. This will cause the columns to fill the last page of the
report automatically. Unfortunately this isn't a solution to display
horizontal grid lines.
[3]
A third approach is adding an extra table directly below your table
with the same size of columns. Using the same method as from the first
solution you could fill the second table to represent the empty rows.
You'll probably have the same issue as with the first solution when
dealing with multi-line rows though.
I believe solution [1] and [3] will offer the most exact solution, if you're willing to do the math. If you don't want any horizontal lines then I suggest using approach [2].
Using an image to overlay the borders is of course another option but then you'll have the same issues when dealing with the multi-line rows. If you plan on working with fixed row heights, where you leave space for multi-line cells then this is becomes a valid approach but so does solutions [1] and [3].
Update:
If you only need the filled pages for printing you could make sure you add enough empty rows to fill at least the entire last page, these may go to a new page (1 new page, not 2... you can use a simple calculated guess for this) and exclude the last page when printing.
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 have a report page,and inside of it,near the end of the page there is a 6x3 table. when i run the report,first row is shown in the first page,and the other 5 rows are shown in the second page even if the keep together property is set to True. Does not the Keep Together property mean that keep all the rows together . How can i fix that ? thanks in advance.
The keep together property attempts to keep individual rows on the same page, not all the rows.
i.e, if you have a detailed row that is filled with content spanning multiple lines, that will still be kept together in the same page when possible.
One possible solution might be to put a rectangle in that page, and putting the table inside the rectangle. Not 100% sure it will work, but that is what I would try.
Hope it helps.
I was having the same problem. The solution is to right click on the table, Add Group, and put everything you want unbroken up in the same group.
is it possible to use CSS3 table to make it look like this
+---A---+---B---+---C---+---D---+---E---+
>>>>+---A---+---B---+---C---+---D---+<<<< ---> case 1
+---A---+---B---+---C---+---D---+---E---+
case 1: need to margin-left the first cell right? is it any code that make auto to margin
+---A---+---B---+---C---+---D---+---E---+
+-----A-----+-------B-------+---C---+-D-+ ---> case 2
case 2: colspan is work on the cell width is same. what if the cell width is vary. Is it possible?
all of this code must be in CSS3 and HTML5 only. No use <table>, <tr>, <td> only <div>
Should I convert to use grid instead of using table?
Thank you.
Use tables if it is tabular data, if it isn't then use something else.
From your example where column widths don't match, and where colspans don't do what you want it's hard to see how the data could be tabular data.
A couple of options, colspan can work if you do it the right way. For example setting a colspan of 2 on normal single span cells would allow you to make other cells span to halfway through another column.
Or if it really isn't tabular data then use DIV's and position them apropriatley.
Using tables, you would not be able to vary the width of one rows cells without affecting the width of all the other rows cells though, im not even sure you can dynamically change colspan once the table has been drawn, never tried it to be honest).
In all honesty I suspect you are really looking to solve this using DIV's, as your data really doesn't seem to fit the tabular data model. Tbular data will generally have headers on columns with data corresponding to those column headers in the appropriate column. Your cells seem to be able to move freely and therefore would not be fixed under any particular column header.
I am guessing from the layout that you are possibly creating some sort of calendar? and events can span any distance of time etc across the columns? In which case I personally would prefer divs, although I know some people would prefer using tables.
I'm working on constructing a table using only divs. I began creating the table using percentages to set column widths, but would prefer to just use table-cell and not have to worry about things that way. Only problem is I'm not guaranteed to have the same number of elements in every row.
http://jsfiddle.net/JWvLX/
This example shows what is currently happening in the top two rows, and what I want to happen if a cell is removed/not present in the bottom two rows.
What exactly do I need to do to accomplish this? Is this possible using only divs for tables or will I be forced to use actual tables to get the desired effect.
There's no equivalent for colspan/rowspan in CSS tables, but this Sitepoint post has some trickery you might be able to use.
