How to enter data in JTable?
I have created a JTable.Now,I want to enter data in specific row and column, how can I do that?
Read the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/table.html]How to Use Tables for the basics of using a table.
Once you have data loaded in a table you can change the data in a cell using:
table.setValueAt(....);

How to enter data manually in SQL server mgmt studio 2012
On a new table, I right click and select "Edit Top 200 rows". It looks like I can enter data here but
I dont see a 'commit' button anywhere. If I click outside the cell it generates an error that I have not committed the data.
I just want to enter some picklist data and don't want to script this. How can I just enter data via the gui?
ThanksPlease fill the data row by row. When you enter the data in first row then press enter. Then you should move to next row.
--> Error Message: String or binary data would be truncated
Error message says that, for some column you have let's say varchar(10) but you are entering data with >10 length

Hi all,
I wish to provide a resize button on an application which will resize the data in a table (in most cases just text) as well as the table containing it. Is it possible to directly resize the table or must I change the renderer to draw all of the data bigger? I'm also not sure how to increase the width of the table. Any help would be much appreciated.

}Using JDK 1.4.2Thanks all.
The solution was to use setFont() on the table and its headers. Here's what I put in to increase and descrease the table size (for future reference).
* Increases the size of everything in the table
private void increaseTable()
table.setRowHeight(table.getRowHeight() + INCREMENT);
table.setSize(table.getWidth() + INCREMENT, table.getHeight() + INCREMENT);
for (int i = 0; i < table.getColumnCount(); i++)
TableColumn col = table.getColumnModel().getColumn(i);
col.setWidth(col.getWidth() + INCREMENT / table.getColumnCount());
Font headerFont = table.getTableHeader().getFont();
table.getTableHeader().setFont(headerFont.deriveFont(headerFont.getSize2D()+INCREMENT));
Font dataFont = table.getFont();
table.setFont(dataFont.deriveFont(dataFont.getSize2D() + INCREMENT));
* Decreases the size of everything in the table
private void decreaseTable()
if (table.getRowHeight() > INCREMENT)
table.setRowHeight(table.getRowHeight() - INCREMENT);
table.setSize(table.getWidth() - INCREMENT, table.getHeight() - INCREMENT);
for (int i = 0; i < table.getColumnCount(); i++)
TableColumn col = table.getColumnModel().getColumn(i);
col.setWidth(col.getWidth() - INCREMENT / table.getColumnCount());
Font headerFont = table.getTableHeader().getFont();
table.getTableHeader().setFont(headerFont.deriveFont(headerFont.getSize2D()-INCREMENT));
Font dataFont = table.getFont();
table.setFont(dataFont.deriveFont(dataFont.getSize2D() - INCREMENT));

How can I add data into JTable, for instance ("Mike", "Gooler", 21).
How can I add data into JTable, for instance ("Mike",
"Gooler", 21).You will have very good results if you segregate out the table model as a seperate user class and provide a method to add a row there. In fact, if you use the table to reflect a database table you can add the row inplace using the existing cursor. I believe it's TableExample2 in the jdk\demo\jfc\TableExamples that has a very good example of this.

how can i change my data for a new data in jtable.
tx for help.I had a problem similar to this. I was writing my own table model which would work sometimes and at other times fail similar to what you describe. I ended up printing out the source code to the DefaultTableModel and taking a look at it and then deciding to subclass that class and add my additional functionality as opposed to writing a completely new model and trying to duplicate the DefaultTableModel. My needs were relatively simple and the subclassing fixed the problem. I can change data with no problem in the displayed table. If you're not already subclassing and trying to write your own table model you may want to give this a try. I'd struggled with the problem for several days thinking I'd fixed it and having it come up again. I invested 2 hours doing the subclassing and the problem has never appeared since then. I know I just missed doing something in the table model I was trying to write but my schedule was tight and the subclassing offered a quick fix. Hope this helps!

How to put data in JTable from database
hi everyone,
i want to query the databse and put the result in the JTable and if possible i want to edit some information. For example: i have 5 records in the database query them and place them in JTable and each record has its own status. if i want to change the status For Example: the status of the 4 records are "Cleared" and the other one is "RELEASEd" so if i have JCombo Box to set the 4 records in to RELEASED status and then save the changes is that possible?
thank you

How to import data into JTable from a text file?
thanks in advance!
My guess is you will have to read the data in from the file, parse it, populate some vectors or something and use those vectors to instantiate the JTable. You could use FileReader to read in the data:
FileReader in = new BufferedReader(new FileReader(file));then use StringTokenizer to parse it.

How to enter data in a custom-table
Hi All,
I created a custom-table in sapCRM system. There won't be a place to enter records on the screens. So how can the users enter new records into the table? Is there any other way they can do that.
Regards,
RanjanHi,
In SE11, on "Delivery and Maintenance" tab, make sure your table is "Display/Maintenance Allowed". There could be other settings too, but i know only this one.
Then, once you inside the table, hit F5 or in the upper tool menu, choose "Table Entry-> Create".
Populate mandatory fields and save.
We have done the same in few projects, but only in the Development environment.
There could be other security settings you need to do, since you will be creating entries in Production.

How to save data from JTable multiple rows and columns
Hi Y_Not thanks for your help before...
But what should I do if I want to get/save many data from many column and rows??i don't quite understand your (repeated) question. what is the problem with "multiple rows and columns". Y_NOT and i have shown you ways to access them.
all you need are 2 loops: one around your number of rows and one around the number of columns or vice versa depending in which order you want to save things:
for (int col = 0; col < data.size(); col++) {
for (int row = 0 ; row < data[col].size(); row++) {
// save your data
saveData(data[col].getElementAt(row));
// or use yourtable.getValueAt(row, col);
}this is not a problem of Swing/Java but of simple algorithm...
