    <p>Reading the remark of Kleopatra (her 2nd time she suggested to have a look at <a href="http://javadoc.geotoolkit.org/external/swingx/org/jdesktop/swingx/JXTable.html" rel="nofollow">javax.swing.JXTable</a>, and now I Am sorry I didn't have a look the first time :) ) I suggest you follow the link</p> <p>I had this solution for the same problem: (but I suggest you follow the link above) On resize the table, scale the table column widths to the current table total width. to do this I use a global array of ints for the (relative) column widths):</p> <pre><code>private int[] columnWidths=null; </code></pre> <p>I use this function to set the table column widths:</p> <pre><code>public void setColumnWidths(int[] widths){ int nrCols=table.getModel().getColumnCount(); if(nrCols==0||widths==null){ return; } this.columnWidths=widths.clone(); //current width of the table: int totalWidth=table.getWidth(); int totalWidthRequested=0; int nrRequestedWidths=columnWidths.length; int defaultWidth=(int)Math.floor((double)totalWidth/(double)nrCols); for(int col=0;col&lt;nrCols;col++){ int width = 0; if(columnWidths.length&gt;col){ width=columnWidths[col]; } totalWidthRequested+=width; } //Note: for the not defined columns: use the defaultWidth if(nrRequestedWidths&lt;nrCols){ log.fine("Setting column widths: nr of columns do not match column widths requested"); totalWidthRequested+=((nrCols-nrRequestedWidths)*defaultWidth); } //calculate the scale for the column width double factor=(double)totalWidth/(double)totalWidthRequested; for(int col=0;col&lt;nrCols;col++){ int width = defaultWidth; if(columnWidths.length&gt;col){ //scale the requested width to the current table width width=(int)Math.floor(factor*(double)columnWidths[col]); } table.getColumnModel().getColumn(col).setPreferredWidth(width); table.getColumnModel().getColumn(col).setWidth(width); } } </code></pre> <p>When setting the data I call:</p> <pre><code> setColumnWidths(this.columnWidths); </code></pre> <p>and on changing I call the ComponentListener set to the parent of the table (in my case the JScrollPane that is the container of my table):</p> <pre><code>public void componentResized(ComponentEvent componentEvent) { this.setColumnWidths(this.columnWidths); } </code></pre> <p>note that the JTable table is also global:</p> <pre><code>private JTable table; </code></pre> <p>And here I set the listener:</p> <pre><code> scrollPane=new JScrollPane(table); scrollPane.addComponentListener(this); </code></pre>

    1. COas far as I can see, this is a (very brittle) hack: it doesn't update on user changing a column width. Again, I would suggest you look into the source code of JXTable - it has an additional property horizontalScroll which triggers filling the available width if the sum of column prefs is less than the current width and shows a horizontal scrollbar otherwise

    2. COI Know it does not react to the user changing the table widths manually, in that way it's a hack... but again: it's better than suggested above. But you made me curious to JXTable.... I will have a look there! (and nice to walk in to you again on a table subject :) )

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
