Updates about Enhanced Database Ranges.

[Akash Shetye]

Hello all,

The progress so far is:
+Reading OOXML data from /styles.xml for Table styles.
+Imports Table Style Elements successfully, for first-second column
and first-second row data.
+Imports the Table styles as a whole represented by the
ScDBDataFormatting class in calc, also imports the table style name
+Nearing completion of associating ScDBData ranges with related
ScDBDataFormatting objects. This means processing the /table/*.xml
files' <tableStyleInfo> tag.
