Making no claim to understanding tcl; what the code appears to be doing is:

  1. for each row in the table;
  2. query the text for each column within that row;
  3. split that text on newlines;
  4. find the maximum number of lines in any column within that row;
  5. 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().
