Hi,
For the moment there is no such option to remove the column but it's a good idea that I put in my TODO list.
You can remove the column by editing the view "productmarket | form_price".
You will have to remove
<th class="title"><?php
echo JText::_('PRICE_WITH_TAX');
?></th>
Replace
<td class="hikam_price">
<input type="hidden" name="price[<?php echo $i;?>][price_id]" value="<?php echo @$price->price_id;?>" />
<input size="10" type="text" id="hikamarket_price_<?php echo $i;?>_price" name="price[<?php echo $i;?>][price_value]" value="<?php echo @$price->price_value; ?>" onchange="window.productMgr.updatePrice(<?php echo $i; ?>, false)" />
</td>
<td class="hikam_price">
<input size="10" type="text" id="hikamarket_price_<?php echo $i;?>_with_tax" name="price_with_tax_<?php echo $i;?>" value="<?php echo @$price->price_value_with_tax; ?>" onchange="window.productMgr.updatePrice(<?php echo $i; ?>, true)"/>
</td>
By:
<td class="hikam_price">
<input type="hidden" name="price[<?php echo $i;?>][price_id]" value="<?php echo @$price->price_id;?>" />
<input size="10" type="text" id="hikamarket_price_<?php echo $i;?>_price" name="price[<?php echo $i;?>][price_value]" value="<?php echo @$price->price_value; ?>" />
</td>
And also replace:
<td class="hikam_price">
<input type="hidden" name="price[{id}][price_id]" value="" />
<input size="10" type="text" id="hikamarket_price_{id}_price" name="price[{id}][price_value]" value="" onchange="window.productMgr.updatePrice({id}, false)" />
</td>
<td class="hikam_price"><input size="10" type="text" id="hikamarket_price_{id}_with_tax" value="" onchange="window.productMgr.updatePrice({id}, false)"/></td>
By:
<td class="hikam_price">
<input type="hidden" name="price[{id}][price_id]" value="" />
<input size="10" type="text" id="hikamarket_price_{id}_price" name="price[{id}][price_value]" value="" />
</td>
Best regards,
