title: PHP: Hide row if column returns empty or have specific value
body: <p>I am stuck in this very basic stuff, hope you guys may be able to help me. I did try many solutions but none of them worked.</p>
  
  <p>Through WordPress admin, I am generating the meta:</p>
  
  <pre><code>[
      'label' =&gt; __( 'Option A', ST_TEXTDOMAIN ),
      'id'    =&gt; 'custom_option_a',
      'type'  =&gt; 'text',
      'std'   =&gt; '0',
      'desc'  =&gt; __( 'Enter option A', ST_TEXTDOMAIN )
  ],
  [
      'label' =&gt; __( 'Option B', ST_TEXTDOMAIN ),
      'id'    =&gt; 'custom_option_v',
      'type'  =&gt; 'text',
      'std'   =&gt; 'N/A',
      'desc'  =&gt; __( 'Enter option B', ST_TEXTDOMAIN )
  ],
  [
      'label' =&gt; __( 'Option C', ST_TEXTDOMAIN ),
      'id'    =&gt; 'custom_option_c',
      'type'  =&gt; 'text',
      'std'   =&gt; 'N/A',
      'desc'  =&gt; __( 'Enter option C', ST_TEXTDOMAIN )
  ],
  </code></pre>
  
  <p>where 'std' => '0' returns blank or empty if not modified from backend and 
  'std' => 'N/A' returns N/A</p>
  
  <p>for output of described meta I have:</p>
  
  <pre><code>&lt;table id="custitindetail" class="table abc-properties" data-toggle-section="abc-properties"&gt;
      &lt;tr&gt;
          &lt;th&gt;&lt;?php echo esc_html__( 'Option A', ST_TEXTDOMAIN ) ?&gt;&lt;/th&gt;
          &lt;td&gt;
          &lt;?php echo get_post_meta( $post_id, 'custom_option_a', true ); ?&gt;
          &lt;/td&gt;
      &lt;/tr&gt;               
      &lt;tr&gt;
          &lt;th&gt;&lt;?php echo esc_html__( 'Option B', ST_TEXTDOMAIN ) ?&gt;&lt;/th&gt;
          &lt;td&gt;
          &lt;?php echo get_post_meta( $post_id, 'custom_option_b', true ); ?&gt;
          &lt;/td&gt;
      &lt;/tr&gt;                           
      &lt;tr&gt;
          &lt;th&gt;&lt;?php echo esc_html__( 'Option C', ST_TEXTDOMAIN ) ?&gt;&lt;/th&gt;
          &lt;td class="cust_holiday_itinerary"&gt;
          &lt;?php echo get_post_meta( $post_id, 'custom_option_c', true ); ?&gt;
          &lt;/td&gt;
      &lt;/tr&gt;
      &lt;?php
      }
      ?&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>Now I want to hide the row if meta value in td is 0 or N/A either through PHP code using 'if empty' or jquery. Help me out please.</p>
  
  <p>Thanks.</p>
