I have a tree view with two columns. The first column's text (Numero) is aligned to right and the second is aligned to left. Why is that happening? How can I align the text of the first column to the left? This is the code of the tree view:
<record id="planificacion_resultado_tree" model="ir.ui.view">
<field name="name">Resultados</field>
<field name="model">utepda_planificacion.resultado</field>
<field name="arch" type="xml">
<tree>
<field name="numero"/>
<field name="name" />
</tree>
</field>
</record>
