Show/Hide columns in crystal reports

I am currently working with a couple programmers to create a desktop application that ultimately will create reports for the user using crystal reports. Here is the problem that my programmer is having:

We have a Crystal Report where we will have a max of 10 columns.  We need to show/hide the correct columns that have been laid out on the report based if there is an entry in the Nodes 'column'.  The name attribute will let us know if we are to show/hide the column and the data comes from the Detail section.  Is this possible in CR?  

We have no idea what type of data will come in the details sections, all we know is that we have 10 columns for the user to select to show on the report.  Will the data line up under the column heading?  We are being told that the column and detail sections are not linked so the if the data is large it will push the other items over.
<Data>
<column name="Detail1" Display="Cost" />
<column name="Detail2" Display="Net Assets" />
<Detail Detail1="18200" Detail2="427700" Detail3="" Detail4="" Detail5="" Detail6="" Detail7="" Detail8="" Detail9="" Detail10=""/>
<Detail Detail1="18201" Detail2="427701" Detail3="" Detail4="" Detail5="" Detail6="" Detail7="" Detail8="" Detail9="" Detail10=""/>
<Detail Detail1="18202" Detail2="427702" Detail3="" Detail4="" Detail5="" Detail6="" Detail7="" Detail8="" Detail9="" Detail10=""/>
</Data>

Can anyone help me with this?

You can supress the column heading based on what the user has selected. To do that

1. Click on column heading --> go to "format editor" --> check "Supress" check box and click on the formula editor icon next to it.

Here you set the condition when you would like to hide the column heading. Let me know if this helps.

What version of CR?
how are you passing the variables into crystal?
I use XI, if I understand your question correctly, it seems to me you can create a formula variable to store an entry. If the value is not null then populate the column, use the 'allow to grow' property to handle runovers.

We are using Crystal Reports XI.

What do you mean by variables?  We are passing the XML, is that what you mean?

Are you trying to allow the user to select the fields and then build a report based on that?

Will all the fields be strings?

DO the numbers need to be treated as numbers or can they be used as strings?

Yes we have to treat them as numbers as we have to sum the details.

Hold the 'node' column value in a subreport. this will allow you to isolate the number, as well as pass the value back and forth as needed.
