With writer now able to handle table styles (bug 34391), as well as import and export ODF table styles, the importing and exporting of OOXML table styles is the next step forward. Table styles are defined in the /word/styles.xml file as multiple <w:style w:type="table"> tags, and here is the default style assigned to inserted tables. <w:style w:type="table" w:styleId="TableGrid"> <w:name w:val="Table Grid" /> <w:basedOn w:val="TableNormal" /> <w:uiPriority w:val="59" /> <w:rsid w:val="00CA4017" /> <w:pPr> <w:spacing w:after="0" w:line="240" w:lineRule="auto" /> </w:pPr> <w:tblPr> <w:tblInd w:w="0" w:type="dxa" /> <w:tblBorders> <w:top w:val="single" w:sz="4" w:space="0" w:color="auto" /> <w:left w:val="single" w:sz="4" w:space="0" w:color="auto" /> <w:bottom w:val="single" w:sz="4" w:space="0" w:color="auto" /> <w:right w:val="single" w:sz="4" w:space="0" w:color="auto" /> <w:insideH w:val="single" w:sz="4" w:space="0" w:color="auto" /> <w:insideV w:val="single" w:sz="4" w:space="0" w:color="auto" /> </w:tblBorders> <w:tblCellMar> <w:top w:w="0" w:type="dxa" /> <w:left w:w="108" w:type="dxa" /> <w:bottom w:w="0" w:type="dxa" /> <w:right w:w="108" w:type="dxa" /> </w:tblCellMar> </w:tblPr> </w:style> Tables are associated with a table style (<w:tblStyle>) in /word/document.xml and define which properties/elements of the style are visible on the table or not (<w:tblLook>). <w:tbl> <w:tblPr> <w:tblStyle w:val="TableGrid" /> <w:tblW w:w="0" w:type="auto" /> <w:tblLook w:val="04A0" w:firstRow="1" w:lastRow="0" w:firstColumn="1" w:lastColumn="0" w:noHBand="0" w:noVBand="1" /> </w:tblPr> </w:tbl> More details can be found in the links below http://officeopenxml.com/WPstyleTableStyles.php
