PHPExcel border styles are defined as constants in PHPExcel_Style_Border class. The solid ones are BORDER_THIN, BORDER_MEDIUM and BORDER_THICK. However, the medium and thick ones are way too thick for my needs. Is there a way to manually set the border thickness?

    PHPExcel border styles are defined to mimic those available in MS Excel itself
    The ECMA OfficeOpenXML specification (3rd Edition) defines available border styles in the ST_BorderStyle section of the document (section 18.18.3, pages 2671-2673) and defined in the xsd as:

    <xsd:simpleType name="ST_BorderStyle">
    <xsd:restriction base="xsd:string">
    <xsd:enumeration value="none"/>
    <xsd:enumeration value="thin"/>
    <xsd:enumeration value="medium"/>
    <xsd:enumeration value="dashed"/>
    <xsd:enumeration value="dotted"/>
    <xsd:enumeration value="thick"/>
    <xsd:enumeration value="double"/>
    <xsd:enumeration value="hair"/>
    <xsd:enumeration value="mediumDashed"/>
    <xsd:enumeration value="dashDot"/>
    <xsd:enumeration value="mediumDashDot"/>
    <xsd:enumeration value="dashDotDot"/>
    <xsd:enumeration value="mediumDashDotDot"/>
    <xsd:enumeration value="slantDashDot"/>
</xsd:restriction>

    This follows the list of border styles defined for the BIFF file format, and I can’t find any provision for defining custom styling or sizes.

    EDIT

    The Complex Border style simply adds colour information to the formatting

    <xsd:complexType name="CT_Border">
    <xsd:sequence>
        <xsd:element name="start" type="CT_BorderPr" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="end" type="CT_BorderPr" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="top" type="CT_BorderPr" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="bottom" type="CT_BorderPr" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="diagonal" type="CT_BorderPr" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="vertical" type="CT_BorderPr" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="horizontal" type="CT_BorderPr" minOccurs="0" maxOccurs="1"/>
    </xsd:sequence>
    <xsd:attribute name="diagonalUp" type="xsd:boolean" use="optional"/>
    <xsd:attribute name="diagonalDown" type="xsd:boolean" use="optional"/>
    <xsd:attribute name="outline" type="xsd:boolean" use="optional" default="true"/>
</xsd:complexType>
<xsd:complexType name="CT_BorderPr">
    <xsd:sequence>
        <xsd:element name="color" type="CT_Color" minOccurs="0" maxOccurs="1"/>
    </xsd:sequence>
    <xsd:attribute name="style" type="ST_BorderStyle" use="optional" default="none"/>
</xsd:complexType>
