Hello,
I cannot get it right, to modify and access specific colums, rows or cells within the SWT table.
I am making a SWT table with the following code:
String[] titles = {Mon, Tue, Wed, Thu, Fri, Sat, Sun};
for (int i=0; i<titles.length; i++) {
TableColumn column = new TableColumn (table, SWT.NONE);
column.setText (titles [i]);
}
for (int i=0; i<titles.length; i++) {
table.getColumn (i).pack ();
}
With the following code I want to delete the table and rewrite the cells of a specific column, which works for the first column of the table:
int countInt = 0;
table.removeAll();
for (Entry e : EntryList) {
TableItem item = new TableItem(table, SWT.NONE);
item.setText(e.EntryNameString);
countInt++;
}
But how to access the cells of the second column?
Why does it not work like Excel with columns, rows and cells?
I only see the first column and the items of it.
Which are per column or row, how are they spread among the table?
Why does the SWT table not have rows?
I googled the whole night long and the eclipse documentation is not useful either. 
Please help!

I'm not sure exactly what you are trying to do. However, if you need to
modify the text of multiple columns of same row, then you could use
either of these APIs :
item.setText (columnIndex, String)
item.setText (String[])
where 'item' corresponds to a particular row, that can be obtained
through table.getItem(rowIndex)
So, SWT maintains multiple columns per row for every table - which is
what you are looking for. So, everything is accessible through the
available APIs.
If I am missing something here, please let me know whether you are
looking for something else.

I don't understand why you removed all table items in your initial
posting. You don't need that for a proper iteration. Praveen did
already describe what you should do. Here a complete snippet (A
variation of SWT snippet 38) that shows how to realize that (I use
Java 1.5 features in the code):
public class Snippet38Iterate {
public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new GridLayout());
Table table = new Table(shell, SWT.MULTI | SWT.BORDER
| SWT.FULL_SELECTION);
table.setLinesVisible(true);
table.setHeaderVisible(true);
GridData data = new GridData(SWT.FILL, SWT.FILL, true, true);
data.heightHint = 200;
table.setLayoutData(data);
String[] titles = { "A", "B", "C", "D", "E", "F", "G" };
for (int i = 0; i < titles.length; i++) {
TableColumn column = new TableColumn(table, SWT.NONE);
column.setText(titles[i]);
}
final int rows = 10;
// Just generate all rows:
for (int i = 0; i < rows; i++) {
new TableItem(table, SWT.NONE);
}
final int cols = table.getColumnCount();
// Iterate through all items from top to bottom
// and from left to right:
for (int i = 0; i < rows; i++) {
TableItem item = table.getItem(i);
for (int j = 0; j < cols; ++j) {
item.setText(j, String.format("[%s, %s]", i + 1, j + 1));
}
}
for (int i = 0; i < titles.length; i++) {
table.getColumn(i).pack();
}
shell.pack();
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
}
