Hi,

I want to hide a column in a report at runtime. What I do is to set
visibility for the column according to a parameter passing at runtime. I
have 3 columns in the report, column1, column2, column3. My method work to
hide a column.

The problem is if column2 is hidden, there is empty space left between
column1 and column3. The emtpy space is the column2. How can I shrink
column2 if it is invisible?

Are you talking about PDF or HTML output?

select the column and then in the Script associated to the column type
(want2displayColumn is a parameter used here to switch between showing the
column or not):

if(params["want2displayColumn"]==true)
this.getStyle().display="block";
else
this.getStyle().display="none";

When I select a column in my table and open the Script tab, it says "This
element has no methods". Which I interpret as "columns do not have
methods". So I am confused about the instructions below ("select the column
and then in the Script associated..."). I want to hide the column, thereby
shrinking the table width.

I am also having a similar problem:

element has no methods".
Please advise.

Hi. There is a filter associated to the table, Try to use that instead of
this.display="none"/"block"

hi. the script is associated to the element inside the cell rather than
with the cell.

Thanks for the help! When I set the visibility condition individually on the header "label" cell and the detail "data" cells it worked fine. I chose the "Visibility" property - selected the checkbox to "Hide Element" , "For all outputs". I used the same expression to evaluate (either "true" or "false") on both the cells. The column (header + detail rows) then disappeared in runtime, based on the return value of the expression.

Yes, this works, but (for me) it does not shrink the table width. I would
like to BOTH hide the column and shrink the table width. 'birt-user'...are
you able to shrink the table width? What version of Birt are you using?
Thanks.

Yes, when the column disappeared, the table width also shrank.
Also, I tried without setting the Visibility condition and included "Data" expression on both the header and the detail rows. When the expression does not return any value(based on the conditional expression), the table displays with the rest of the columns and completely hides this column and shrinks the table width.

I am using BIRT 2.0.1 version.

Ahh...the dilemma! I have some columns that should be narrow, and others
that should be wide. If specify column-widths, then my report looks nice,
but when the user selects a column to hide, the table-width does not shrink
(groan). If I do not specify column-widths, then the report looks ugly
(groan) but when the user selects a column to hide, the table-width shrinks
nicely. You can't have it both ways!

The remedy is to allow column-widths to be set at runtime. Looks like an
enhancement request to me.

if you want to shring the table, try to add a highlight filter on the rows
or columns. each table has associated the highlight filters.
