Tricky table formatting using jstl

I have an array List of elements of size for example50. I need to retrieve the elements as shown above and print them as a two dimensional table as below:
The steps involved as below:
1. I need to check the size of array say Z
2. Divide it by 10 (ceil Z/10) and find the number of columns needed
3. Print the elemnts from the ${List} as follows:
1stelement   11thelement    21stelement   31stelement    41stelement
2ndelement   12thelement   22ndelement   32ndelement   42ndelement
10thelement   20thelement   30thelement    40thelement    50thelement I tried few methods and I feel it as bit trick for me as a beginner. I would appreciate very much if someone could help me! Thanks.

So the requirement is to split the list into 10 rows, and as many columns as are required?
Here is some basic code:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
<%@ page import="java.util.*" %>
<html>
<body>
<%
int numToDo = 50;
List listOfNumbers= new ArrayList();
for(int i=0; i<numToDo; i++){
       listOfNumbers.add(Integer.valueOf(i));
pageContext.setAttribute("List", listOfNumbers);
int numCols = (int)Math.ceil(listOfNumbers.size() / 10.0);
pageContext.setAttribute("numCols", new Integer(numCols));
%>
<table>
       <c:forEach var="entry" items="${List}" varStatus="status">
         <c:if test="${status.index % numCols== 0}">
           <tr>
         </c:if>
             <td>${entry}</td>
         <c:if test="${status.index % numCols== (numAppsPerLine-1)}">
           </tr>
         </c:if>
       </c:forEach>
</table>
</body>
</html>The issue is how to calculate how many columns correctly.
JSTL/EL doesn't have rounding math operators available, so I did that bit in scriptlet code for a quick/dirty approach.
Apart from that calculation, it is all standard JSTL/EL.
Basically it just keeps track of the index (using the varStatus variable) and starts/ends a table row as necessary.

Table format used in the 'sums' table

Hello,
If you ask numbers to insert a table of the type 'sums', then a table is inserted which has a a thick white line above the last row.
I have many tables and I would like to format them like the sum table.
Therefore, I would like to know how I can insert a thick white line above the last row?
Thanks,
Sanjay

Get-rid of the format we get using Get-ADuser in a CSV. Send CSV data in an email in table format

Hi,
I am using get-ADuser in order to extract a few AD attributes of some users. I export the users and their respective attributes to a CSV. However, the output in CSV i get has the following format in each cell for its AD attribute.
@{description=<Value>} or @ { info=<Value>}
I have tried to use Expandproperty switch in order to get rid of it but it does not accept null values and hence if a user has no value for a said attribute, the previous value is copied for that user too. However, without expand property it gives me the
above format in the output.
$Desc = Get-ADUser $Username -Properties description | select description
I would like the cells to contain only values and not this format along.
Also, once I have the CSV with values I would also like to copy the values from CSV in an email in the form of a TABLE. I have been able to copy the content in an email using the following however, this in not in a table format.
$mail = Import-Csv $newlogonfile | Out-String
Please HELP!

Yes I am already using Export-Csv but still getting the same kind of format in output :-
$Username = $Event.Properties[5].Value
$Title_var = get-aduser $Username -properties Title | select Title
$Ofc_phone = get-aduser $Username -Properties OfficePhone | select OfficePhone
$Info_var = get-aduser $Username -properties info | select info
$Display_Name = get-aduser $Username -properties DisplayName | select DisplayName
$Mail = Get-ADUser $Username -Properties Mail | select Mail
$Desc = Get-ADUser $Username -Properties description | select description
$Props = @{
User = $Event.Properties[5].Value;
TimeCreated = $Event.TimeCreated;
LogonType = $Event.Properties[8].Value;
DCName = $Event.MachineName;
Workstation_address = $Event.Properties[18].Value;
Title = $Title_var;
OfficePhone = $Ofc_phone;
Info = $Info_var;
DisplayName = $Display_Name;
Description = $Desc;
EMail = $Mail
$LogonRecord = New-Object -TypeName psobject -Property $Props
$Result += $LogonRecord
$Result | Export-Csv -Path $logFile -append -UseCulture -NoTypeInformation # Log it to CSV
OUTPUT has values in this format in the CSV :-
@{info=} @{description=abc} @{DisplayName=} @{Officephone=}
@{Mail=[email protected]}

How to format a calculated field using JSTL

Hi,
I have one field as following:
<input type="text" class="fixedInput" name="grossRevenue<%=i%>" value="<%=((LineOfBusinessMetrics)lineOfBusinessMetricsList.get(i)).getGrossRevenue().setScale(2,BigDecimal.ROUND_HALF_UP)%>" size="16" onfocus="this.blur()" /></td>
In the above line of code, I have one list called lineOfBusinessMetricsList. From this list, I am fetching the object of LineOfBusinessMetrics, from this object, I am fetching the value of Gross Revenue and casting it to LineOfBusinessMetrics.
Now I am trying to format the Gross Revenue using JSTL tag "fmt" as following:
<td class="grey3"><input type="text" class="fixedInput" name="<c:out value='grossRevenue${i}'/>" value="<fmt:formatNumber type="number" value='${lineOfBusinessMetricsList.grossRevenue}' minFractionDigits="2" maxFractionDigits="2" />" size="16" onfocus="this.blur()" /></td>
The above modified code wth JSTL tag fmt is not working correctly.
Can anyone help me to get this code work.
Thanks in Advance,
Vijay

You must submit the page to do it with PL/SQL. If you do not want to submit the page, you must do it with JavaScript.

Extract the table formated data using itextsharp in c#

I have one pdf file in which i need to extract table formated data in a specific format by each filed.I tried by using itextsharp but data comes in unspecified format. Can any one help me on this.This is very useful for me.
please find attchement for pdf and their fields

like wise all fileds.

Hello Manideep Lakkakula,
As ITextSharp is a library from here
http://sourceforge.net/projects/itextsharp/ and also PDF is third party product, I'm afraid you have to post on specific forum about ITextSharp library instead of here. C# is just a language forum.

Generally it's best to post in the Hey Scripting Guy forum, they are scarily good in there. Someday i hope to give an answer so perfect that not even jrv can improve on it.
Your approach might be possible but it's not the way i'd do it. The ConvertTo-HTML is pretty clever, it works well with arrays of objects. If you were to load each result into a custom PSObject then add that to an array of them for later processing you can
get the table formatting almost for free.
I haven't worked with SQL queries in a bit but this might work, it seems ok when i put token results in for the SQL result.

pls provide sample code for it.
I would be thankful to u guys,
Thanks & Regards,
Raghu.

UserName and Password and display in a table format
.Really, really bad idea.
There is never any need, in any implementation to display or even keep actual passwords.

May i know how to get it in a tabular format as an

Something else? Then you need to explain exactly what the destination is and what defines it as 'tabular'.

You'll have to use the destype DELIMITEDDATA to render your Report in CSV format. Then set the mime type to Excel. I don't know the exact syntax, so please do a search in metalink for "reports excel" for examples and more info.
