Column width in JTables.Help needed!!!!
Hi
I am trying to print out a JTable and have had a few problems along the way but have managed to solve them all so far apart from this one. When the JTable is shown on screen it doesn't make the columns wide enough . I ahev managed to find some code from these forums but it doesnt resize correctly if the Column headings contain more text than any of the data (If you know what i mean). Below is the code i am using
public void sizeAllColumnsToFitData (JTable table) {
for (int col = 0; col < table.getColumnCount (); col++) {
TableColumn curColumn = table.getColumn (table.getColumnName (col));
if (curColumn == null)
continue; // not a valid column skip
// Translate to the model
int modelColumn = curColumn.getModelIndex ();
// Loop for all rows in this column looking for the widest piece of data
int maxColumnWidth = 0;
for (int row = 0; row < table.getRowCount(); row++) {
TableCellRenderer curCellRenderer = table.getCellRenderer (row, modelColumn);
Object value = table.getValueAt (row, modelColumn);
Component curRenderComponent = curCellRenderer.getTableCellRendererComponent(table, value, true, true, row, modelColumn);
Dimension cellDimension = curRenderComponent.getPreferredSize ();
if (cellDimension.width > maxColumnWidth)
maxColumnWidth = cellDimension.width;
// Set the column width to fit the maximum
Dimension cellSpacing = table.getIntercellSpacing ();
curColumn.setPreferredWidth (maxColumnWidth + (cellSpacing != null ? cellSpacing.width : 1));
}I pass my table into here and it works fine apart from in doesnt take into consideration the size of the headings. Please Help ME!!!!

Resize column width for JTable without column headers?
Hi,
I find that for me to resize columns of a JTable by using
mouse dragging, I MUST have column headers and then drag
column headers to resize them. Is my understanding correct?
Actually, I need to have a table without header columns.
How can I use mouse to resize column width by dragging?
The background for this request is that I am putting a
complex table as another table's column header and I hope to
be able to resizing the complex table by mouse dragging.
Thanks very much,
DavidHi,
I think you have mistake there. Try
<style type="text/css">
table.apexir_WORKSHEET_DATA td {
white-space:nowrap !important;
td[headers="DESCR"] {
width:300px !important;
max-width:300px !important;
#apexir_DESCR {
width:10px;
max-width:300px !important;
</style>And you can try add
table.apexir_WORKSHEET_DATA {
width: 100% !important;
table-layout: fixed !important;
}Regards,
Jari

How to set the column width of JTable
I want do remember the column width and write it to a file, when the window is started , the column width is read from the file and the table is set as that. I also want the column width is not fixed and can be changed by mouse.But I am always failded.
How to do? would you please help me!
Thanks a lots.To "remember" the column widths, add a mouse listener to the table header. Upon mouseReleased(), get the column widths and save them to your file. When the application starts next time, get the stored widths and set them using:
table.getColumn("XXX").setPreferredWidth(...);
By default, your columns are adjustable, but you can use:
table.getTableHeader().setResizingAllowed(true); -
I have two columns in a JTable and I am trying to set the column width for the first.
I am trying to this by
getDataTbl().getColumnModel().getColumn(0).setHeaderValue("Index");
getDataTbl().getColumnModel().getColumn(1).setHeaderValue(" Data ");
int width = ((String)getDataTbl().getColumnModel().getColumn(0).getHeaderValue()).length();
getDataTbl().getColumnModel().getColumn(0).setPreferredWidth(width);
but it doesn't reset the width. I want the first column width to be smaller than the second which should be much larger width.
Any suggessions to this?
Thanks.Hi there
Use this JTable method
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);This should solve your resize problem

Can't set custom column widths in JTable
I'm trying to set custom columns widths. They are set as I wish but then they are reset to default values (all columns have the same size). This is caused by method JFrame.setVisible(true) which invokes JTree.setWidthsFromPreferredWidths(). It can be investigated from following stack trace printed when a column being resized (see below).
How to prevent this auto width sizing?
P.S. can't override JTable.setWidthsFromPreferredWidths(); seems it's private
table = new JTable(model) {
public void columnMarginChanged(ChangeEvent event) {
new Exception("stack trace").printStackTrace();

I want to display JTextArea
which should be scrollable. each cell of my JTable contains a JTextArea and I want to have scrollbars appear only for those JTextArea where the text doesn't fit in the JTextArea. I have tried using Cell Renderer JTextArea in ScrollPane, but still the scroll bars doesn't appear. I have put my JTable in a scrollPane. But I also need scrollBars to appear for my individual JTextAreas in the cells. Any help is appreciated. Here is a small code and hope it helps:

can any one help me in getting the scroll bars on my JTextArea too. In my main program I am doing this
JScrollPane scroll = new JScrollPane( table );
it puts scrollbars arround the whole table but I also need scrollbars to come arround each JTextArea too.

Hello all,
i am trying to extend the JTable class to create a table in which i can enter numbers. I would also like to channge the default renderer so i can change the colours of the cell lines. Aslo, i would like to add colum headers and row headers. I want the colum and row headers to be namesd after the dimensions passed to the new Table class. This may seem trivial to some, but i cant seem to get it going. I know i should have to extend the abstract table model, but i dont know what to put into it.
The only bit of code i have got going so far which definatly works in the class definition. I cant seem to find any good documentation about how to do the abogve...the sun tutorial only confuses me..could anyone please please help.
Thanks in advance, regards, Rupesh

JTable - Horizontal Scrollbar - Column Width
I wish to add a horizontal scrollbar(which for some stupid reason Java has not included) to my JTable which is inside a JScrollPane and also make sure that the width of the fourth column is longer and can fit the String that i wish to display. Now, i have searched the forum for solutions but none of them seem to work. The setting of the column width with the help of TableColumnModel does not seem to work and not to mention the fact that when i turn auto rezise off for the JTable, the JTable does give me a horizontal scrollbar but then it makes the columns so less in width that i have gray area left on the right hand side and the setColumnsToFit method does not work. I have five columns and here is the code, any help would be greatly appreciated Thanks:
excepTable = new JTable(excepTableModel);
excepTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
int width = 100;
TableColumnModel tcm;
TableColumn tc;
for(int i = excepTable.getColumnCount(); i > 0; i--)
tcm = (TableColumnModel)excepTable.getColumnModel();
tc = tcm.getColumn(i);
if(i == 3)
width = 400;
tc.setWidth(width);
tc.setMinWidth(width);
tc.setMaxWidth(width);
tc.setPreferredWidth(width);
width = 100;
exScroller = new JScrollPane(excepTable);.I've set a horizontal scrollbar by using 'table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);You are welcome.

Now compare the tutorial code with your code to determine what is different.

Column width issue in SharePoint 2010 Reports using SSRS webpart
Dear sir,
We need to adjust column width for output of reports. We are using SSRS webpart to generate reports. It is taking unexpected column width.
We show that dynamically we cannot set the column width but we are passing the query statically is there any way or chances to mange column width.
Please help.If it's important, I'd suggest ringing Microsoft Premier Support and logging a call. The working world is probably just getting back to their offices.
For both columns, you can think about some JQuery to isolate the appropriate selectors and just reside them in the page rendering. You'll need JavaScript enabled in your browser for this but this code within a CEWP should do the trick.
<!--ADJUST TABLE COLUMN WIDTH-->
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"
type="text/javascript"></script>
<script type="text/javascript">
$(function(){
$("TH.ms-vh2-nograd:contains('Status description')").css("width", "150px");
$("TH.ms-vb:contains('Type of Work')").css("width", "150px");
</script>
You'll need to link to a JQuery instance of course and change the capture text for your columns.

Controlling Column Width in Report Region
I have a report region based on a simple select statement. I'd like the table to be the full width of the region and I'd like the columns to be spaced evenly so that they are also the full width of the region. I have figured out how to set the table width via Report Attributes Substitution, but I am unable to set the column width. Any help would be greatly appreciated.

How to size JTable Column width?? Need help
Using the following logic to size column width, but only the 1st column is sized. How can I get the other columns sized??
int widthsSummary[] = {340,60,150,60,60};
for (int i=0; i<1; i++)
column = getScrollPaneTableSummary).getColumnModel ().getColumn(i);
column.setMinWidth(widthsSummary);
column.setMaxWidth(widthsSummary[i]+50);
column.setPreferredWidth(widthsSummary[i]);First, take a look at your for loop
for (int i=0; i<1; i++)i starts at 0 and cannot be equal to or greater than 1. This loop will only occur once, when i = 0.
Second, take a look at your set...Width calls
column.setMinWidth(widthsSummary);
column.setMaxWidth(widthsSummary+50);
column.setPreferredWidth(widthsSummary); widthsSummary is an array. You need a number to set widths. Try ...set...width(widthsSummary);
Hope that helps.
