Making no claim to understanding tcl; what the code appears to be doing is:
- for each row in the table;
- query the text for each column within that row;
- split that text on newlines;
- find the maximum number of lines in any column within that row;
- set the row height for that row accordingly.
SOmething roughly equivalent in Perl terms to: my $maxRows = $tableMatrix->cget( -rows );
my $maxCols = $tableMatrix->cget( -cols );
for my $r ( 1 .. $maxRows -1 ) {
set $maxHeight = 1;
for my $col ( 0 .. $maxCols - 1 ) {
my $text = $tableMatrix->getText( -row => $row, -col => $col )
+;
my $nLines = scalar split "\n", $text;
if( $nLines > 1 and $maxHeight < $nLines ) {
$maxHeight = $nLines;
}
}
$tableMatrix->cset( row => $row, height => $maxHeight );
}
You'll have to work out the appropriate methods to call for what I've shown as getText() & cset().

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
