Java - how to display and edit block of 250 numbers in JavaFX - javafx-8

I need to be able to display and allow the user to edit an array of 250 int values in a table/grid. It would be best if they were arranged in 25 rows and 10 columns with row and column headings. It should look and work a bit like an excel table. How should I go about this?

Crystal Reports - Create subreport with column range [col1...col60] as datasource?

I am adept in both SQL and CR, but this is something I've never had to do.
In CR, I load a table that will always contain 1 record. There is a range of columns (like Column1, Column2 ... Column60). (bad design, I know, but I can't do anything to change that).
Thanks to this old design I have to manually add each column in my report like this:
-----------
| TABLE |
-----------
| Column1 |
| Column2 |
| Column3 |
| ... |
-----------
Now I would like to be able to create a subreport and create a datasource for it in such a way that [Column1...Column60] becomes a collection [Row1...Row60]. I want to be able to use the detailsection of the subreport to dynamically generate the table. That would save me a lot of time.
Is there any way to do that? Maybe a different approach to what I had in mind?
Edit
#Siva: I'll describe it the best way I can. The table exists out of 500+ columns and will only hold 1 record (never more). Because normalization was never taken into account when creating these tables (Objective C / DBF ages) columns like these: Brand01,Brand02,Brand03...Brand60 should have been placed in a separate table named "Brands"
The document itself is pretty straight forward considering there's only one record. But some columns have to be pivoted (stacked vertically) and placed in a table layout on the document which is a lot of work if you have to do it manually. That's why I wanted to feed a range of columns into my subreport so I can use the detail section of my subreport to generate the table layout automatically.
Ok got it... I will try to answer to the extent possible...
you need to have 2 columns in report that will show the 60 column names as 60 rows as 1st column and 60 column data as 2nd column. For this there are two ways that I can think of.
if columns are static and report need to be developed only once then though its a tough job manually create 120 formulas 60 for row names where you will write column names and 60 for data for respective columns and place in report since you have only one record you will get correct data. Like below:
formula 1:
column1 name // write manually
Formula 1:
databasefield for column1 // this has data for column1
Above will be one row in report like this you will get 120 formulas 60 rows and you don't need sub report here main report will do the job.
Since you are expecting dynamic behavior (Though columns are static), you can create view from database perspective or datatable (Please note I have no idea on datatable use it as per your convinience).
Create in such a way that it has 2 columns in table and in report use cross tab that will give you dynamic behaviour.
In cross tab column1 will be rows part and column 2 will be data.
Here also I don't see any requirement for sub report you can directly use main report. If you want sub report you can use aswell no harm since you have only 1 record

Two different detail sections side-by-side with two different tables?

I use two different excel files in one report. The columns of the excel files are stored in fields. I want to show the columns side-by-side:
Excel Data 1:
ID Name
1 Blub
2 Blub2
Excel Data 2:
ID Income
10 10134
20 134343
So the result should look like this:
ID Name ID Income
1 Blub 10 10134
2 Blub2 20 134343
I tried it with two different Detail sections (I have to use detail sections) and activate the overlaying of underneath sections for both detail sections.
The result looks like:
ID Name ID Income
1 Blub
2 Blub2
10 ....
20 ....
That is because we use a function model of BW that will give us the data back like this:
ExcelFile ID Name Income
1 1 Blub
1 2 Blub2
2 10 10134
2 20 134343
I can not use sub reports and cannot use single fields for each value because there are 100 cells in there...
Does anyone knows a solution?
You have to split your detail row vertically to do that. Something similar already solved by me here. Be careful when you width of data size.
If it doesn't help you enough, feel free to ask with additional questions.
I tried it:
Data looked like this:
After that it looked like this:
I did a Grouping on the names "GS_FC...." so there are two groups in the report. Than I put the Field which contains the name of the Excel File (GS..._TFCF and GS...._NFD) in the Detail section with this settings:
Is this the right thing to do?

SSRS Double row headers and data display for printing

** I'm using SSRS2008 R2
I have a report that the users would like to see in a printable pdf.
Problem is there are several columns, potentially too many to fit on a printed 8.5x11 paper.
One of the concepts they suggested was a stacked header/data display, like breaking the columns into 2 rows, so 2 rows of data (for John and Bill) would look like this:
NAME START_DATE STATE COMPANY
ACCOUNT BALANCE END_DATE
-------------------------------------------------------
John 1/20/2016 NY GE
10076 $100.00 2/20/2016
-------------------------------------------------------
Bill 5/13/2016 MA Netflix
00013 $150.00 12/31/2016
-------------------------------------------------------
This leads me to 2 questions:
Is there a way to do this with a tablix?
AND/OR in addition, is there a way to set a default property on the report so when the report is exported to pdf and to print, that it defaults to fit all columns on one page (therefor shrinking the font size to fit on page?)
For anyone that cares - Apparently this can easily be achieved by dragging a Tablix onto the work area, right clicking the header row, adding a new row underneath (basically becomes header row 2), then do the same thing to the details row - however make sure to insert row - Inside group. That allows you to have stacked header and data rows and you can copy / paste headers and row values in whichever row you'd prefer.
it will work if you make all the columns on the same height not unequal. If all the columns has same height, then while exporting to pdf/excel and print it will come in the same page.

Select value in table in tableau

I am quite new to Tableau, so have patience with me :)
I have two tables,
Table one (T1) contains all my data with the first row being Year-Week, like 2014-01, 2014-02, and so on. Quick question regarding this, how do I make Tableau consider this as a date, and not as string?
T1 contains a lot of data that looks like this:
YearWeek Spend TV Movies
2014-01 5000 42 12
2014-02 4800 41 32
2014-03 2000 24 14
....
2015-24 7000 45 65
I have another table (T2) that contains information regarding some values I want to multiply with the T1 columns, T2 looks like:
NAME TV Movies
Weight 2 5
Response 6 3
Ad 7 2
Version 1 0
I want to create a calculated field (TVNEW) that takes the values from T1 of TV, and adds Response(TV) to it, and times it with the weight(TV),
So something like this:
(T1[TV]+T2[TV[Response]])*T2[TV[Weight]]
This looks like this for the rows:
(42+6)*2
(41+6)*2
(24+6)*2
...
(45+6)*2
So the calculation should take a specific value from T2, and do the calculation for each value in T1[TV]
Thanks in advance
The easy answer to your question will be: No, not natively.
What you want to do sounds like accessing a 2 dimensional array and that's not really the intention of Tableau. Additionally you have 2 completely independent tables without a common attribute to JOIN on. Tableau is just not meant to work that way.
I cannot think of a way to dynamically extract that value (I assume your example is just that, an example; and in your case you don't just use two values in the calculation, otherwise you could create 2 parameters that you can use in your calculated fields)
When I look at your tables it looks like you could transpose and join them that they ideally look like this: (Edit: Comment says transposing is not an option)
Medium Value YearWeek Spend
Movies 12 2014-01 5,000
Movies 32 2014-02 4,000
Movies 14 2014-03 2,000
Movies 65 2015-24 7,000
TV 42 2014-01 5,000
TV 41 2014-02 4,000
TV 24 2014-03 2,000
TV 45 2015-24 7,000
and
Medium Weight Response Ad Version
TV 2 6 7 1
Movies 5 3 2 0
Depending on the systems you work with you could already put it in one CSV or table so you wouldn't have to do a JOIN in Tableau.
Now you can create the first table natively in Tableau (from Version 9.0 onwards), if you open your data source, in the Data Source Preview choose the columns TV and Movies, click on the small triangle and then on Pivot. (At this point you can also choose the YearWeek column click on the triangle and Split to create a seperate field for Year and Week. You won't be able to assign the type date to it put that shouldn't give you any disadvantages.)
For the second table I can think of two possibilities:
you have access to a tool that can transpose your table (Excel can do that see: Convert matrix to 3-column table ('reverse pivot', 'unpivot', 'flatten', 'normalize') Once you have done that you can open it in Tableau and join the two tables on Medium
You could create calculated fields depending on the medium:
Field: Weight
CASE [Medium]
WHEN 'TV' THEN 2
WHEN 'Movies' THEN 5
END
And accordingly for Response, Ad and Version
Obviously that is only reasonable if you really just need a handfull of values.
Once this is done it's only a matter of creating a calculated field with
([Value]+[Response])*[Weight]
And this will calculate all the values for your table

BIRT Mathematics on data set

I am pretty new to Birt reporting, i can make simple charts and tables, bet when it comes to some calculation of values from data sets - i have no clue in which direction should i watch.
For example i have this simple data set:
count1 count2 max type lenght
616 3858 21 STEEL 20
723 4432 14 STEEL 40
854 5869 21 ALL 20
838 5225 14 ALL 40
And i would like to have Birt to calculate approximately this:
SUM(count2)/SUM(count1) WHERE type=ALL
so this
((5869+5225)/(854+838))
My question would be how could i get there. At this point i think i would need just the right direction how these kind of operations could be made.
Thanks in advance.
I presume you want to display this value somewhere on the report, like at the bottom of a table where this data is presented. If this is the case then add an aggregation data element to the footer of the table where the data is displayed. In the aggregation data element you will have the opportunity to specify an expression SUM(count2) and a filter condition [type=ALL]. You can then do the division in another data element.
If you want to simply compute the value you described you you could do it with SQL, i.e. SELECT SUM(count2)/SUM(count1) FROM myTable WHERE type='ALL'. You would have to provide the data to the report as a data source which could be in the form of an excel spreadsheet, *.csv, database connection, etc.
So there are a few ways to do this depending on what your requirements are.
