see OpenOffice::OODoc::Styles in particular the section 
building styles from scratch by program is not a recommended practice. It's much more easy to create documents which all the needed styles through an ODF-compliant office software, and to use them as templates in the programs, knowing that it's very easy to retrieve an existing style, to copy it and to re-use it (as is or customised) in new documents.

However, for your relatively simple requirements try this 

#!/usr/bin/perl
use strict;
use OpenOffice::OODoc;

my $doc  = odfDocument(file => 'test.odt', create => 'text');

$doc->createStyle( "border",
  family  => 'table-cell',
  parent  => 'Standard',
  properties => {
    'fo:border'  => "0.05cm solid #000000",
    'fo:padding' => "0.05cm", 
  }
);

$doc->createStyle( "2cm",
  family  => 'table-column',
  parent  => 'Standard',
  properties =>  { 'style:column-width' => "2cm" }
);

$doc->createStyle( "6cm",
  family  => 'table-column',
  parent  => 'Standard',
  properties =>  { 'style:column-width' => "6cm" }
);

$doc->createStyle( "theading",
  family  => 'paragraph',
  parent  => 'Standard',
  properties => {
    -area            => 'text',
    'fo:font-size'   => '13pt',
    'fo:font-weight' => 'bold',
    'fo:color'       => '#000000', # black
    'fo:font-family' => 'arial',
  }
);  
$doc->updateStyle( "theading",
  properties => {
    'fo:background-color' => "#c0c0c0" , # light grey
  }
);  

my @width = ('2cm','6cm','2cm');
my @data = (
  ['S No','Name','Value'],
  ['A1','B1','C1'],
  ['A2','B2','C2'],
  ['A3','B3','C3'],
  ['A4','B4','C4'] );

my $table = $doc->appendTable('tab1',5,3);

for my $c (0..2){
  $doc->columnStyle('tab1',$c,$width[$c]);  
  for my $r (0..4){
    $doc->cellStyle('tab1',$r,$c,'border');
    $doc->cellValue('tab1',$r,$c,$data[$r][$c]);
  }
  $doc->setAttributes($doc->getCellParagraph("tab1",0,$c),'text:style-
+name' => 'theading');
}
$doc->save;
