How to hide row in JTable?

Hi all,
How to hide some specific rows in JTable for user view filtering purpose?
Thanks

Try to use the Table Model.
The "getValueAt" Methode decide what to Display.
So a simple "if" command can hide the complete row - or a single Statement.
public Object getValueAt(int row, int col) {
ArrayList al = new ArrayList();
StueliTeil tabellenzeile = (StueliTeil) getDaten().get(row);
switch (col) {
case 0 :
return tabellenzeile.getUmfang();
case 1 :
return tabellenzeile.getTakt();

How to hide rows of Jtable

i have a table with 200 rows
on a filter action i would like to hide some rows
and back when i say refresh it should be back with the same old table
im using my own tablemodel
any help
thanks

And you'll also have to make sure that the getRowCount() method returns the correct value. When you switch between the "filtered" and "non-filtered" views, if your table model is a subclass of AbstractTableModel, call the fireTableDataChanged() method.

Hidding rows in Jtable

Can anybody help me, please???
I need to hide a row when the value of a column is 0 but I don't want to delete it.

What do you see as the difference between hiding and deleting?
If you "hide" the row, how would the user ever get it back?
Assuming that the table is displaying its information from an array or vector that has been created specifically for its use, removing an element from this vector is not going to actually effect your persitent data until you save it. Although it would remove any 1-1 correspondence between the two data sets.
It is possible to hide a row without removing it from the table's data vector, but it would be awkward and prone to errors. To do so you would have to change the table's getValueAt method to use an alternative index that skips some rows. I would suggest looking at the TableSorter from the swing tutorial for suggestions of how this could be done.

How to remove a row from JTable

Hi!
I'm used to remove rows from JTables getting the model and doing a removeRow(num) like this:
((DefaultTableModel)jTable1.getModel()).removeRow(0);
But with ADF and JDeveloper the model says it's a JUTableBinding.JUTableModel but its not accessible.

Or maybe is just better to refresh data in the jTable but I do not know either like doing it.

2x2 table. 4 empy cells. Can hide rows but not columns. grayed out. argh!

Only one sheet with a single table with 4 cells.
I don't see any merged cells.
Is there any other attribute that prevents columns from being hidden?
I realize that one cannot hide all the columns or all the rows.
I was given a spreadsheet months ago with this problem.
Couldn't figure it out so worked around it by creating a new one and copying over the data.
Still have the original, so I have pruned it down to a 2x2 table that still has the problem!
Sure would like to know what is going on.

You can take a table down to a single visible cell, but no further.
This worked for me to show only cell B2:
Expand the 2 x 2 table using the handle at the lower right to include more than two rows and more than two columns.
Click the header tab for column A and choose Hide Column.
Click the header tab for Row 1 and choose Hide Row.
Grab the handle and drag it up and to the left to collapse the table to a single visible cell.
This was done with a new sheet after placing data in the top left block of four cells. YMMV, of course.

Hide row and cell by cell formatting

Hello,
I am new to both diadem and VBS and I am having difficulties in translating calculations between excel and diadem. I know that diadem doesn't have the same cell by cell formatting that excel does but is there a way to either hide rows that do not meet a certain condition or a way to say use an equation of the form
=IF(H5> 0,J5+M4,0), where H is the conditional column and M is the resultant column?
Thank you

Hello ccimac,
You might want to look at the IIF function to help you solve that particular problem,
Example:
Call Calculate("Ch(""ResultNV"")=IIf( Ch(""Channel1"")>1,Ch(""Channel1""),NoValue)" )
This will create a NEW data channel called ResultNV that checks (in this example) whether a channel called Channel1 is larger than 1 or not. If it is, the value will the the actual channel value, if the values are smaller than 1 the software will replace the values with a NoValue - which is DIAdem's way of saying that a "cell" contains invalid values.
Does that work for your question? Feel free to ask if you have further questions,
