B B
The matches may be separated by an unknown number of lines.
My intention is to group them and add a "group" value in the last col.
For example
A A A
A B A
B B A
or
A A A
B A A
B B A
How do you determine the group value? Why is the third line not B B B?
Quote:
Rest assured that only one of A B and B A will be present and not both.
Any help will be highly appreciated.
A may have matches in addition to B and any number of of them. But in all cases I would like to name the group with the first partner of the first instance, i.e. A in this case.
It would be helpful if you provided more examples from the file.
It might also help if you posted some real data in addition to the abbreviated, single-letter data.

tk::tablematrix::spreadsheet
TableMatrix::Spreadsheet(3pm) perl/Tk Documentation TableMatrix::Spreadsheet(3pm)
NAME
Tk::TableMatrix::Spreadsheet - Table Display with Spreadsheet-like bindings.
SYNOPSIS
use Tk;
use Tk::TableMatrix::Spreadsheet;
my $t = $top->Scrolled('Spreadsheet', -rows => 21, -cols => 11,
-width => 6, -height => 6,
-titlerows => 1, -titlecols => 1,
-variable => $arrayVar,
-selectmode => 'extended',
-titlerows => 1,
-titlecols => 1,
-bg => 'white',
);
DESCRIPTION
Tk::TableMatrix::Spreadsheet is a Tk::TableMatrix-derived widget that implements some bindings so the resulting widget behaves more like a
spreadsheet.
Bindings Added:
o
Row/Col resize handles appear when the cursor is placed over a row/col border line in the rol/col title area.
Dragging these handles will resize the row or column. If multiple rows or columns are selected, then the new row/col size will apply to
all row/cols selected.
Note: With the base Tk::TableMatrix, it is possible to resize the row/cols by dragging on any cell border. To be more spreadsheet-like,
Tk::TableMatrix::Spreadsheet defaults to enable row/col resizing only thru the title row/col dragging. To override this default behavoir,
set the -resizeborder option to 'both' at startup.
o
A popup menu for row/col insert/delete appears when the mouse is right-clicked in the row/col title areas.
o
Cells activate (i.e. the contents become edit-able) only when the cell is double-clicked or the F2 button is pressed. The default
Tk::TableMatrix behavior is for the cell to be activated when the cell is single-clicked.
o
The Escape key causes any changes made to a cell to be canceled and the current selection cleared.
o
The return key causes the the current cell to move down.
o
The tab (or shift tab) key causes the current cell to be moved to the right (left).
o
The delete key will delete the current selection, if no cell is currently active.
o
The Mouse button 2 (middle button) paste from the PRIMARY. (Control-v pastes from the clipboard).
Additional Information
Widget methods, options, etc, are inherited from the Tk::TableMatrix widget. See its docs for additional information.
