Description:
 def getcellslice(self, columnname, rownr, blc, trc, inc=[]):
 """Get a slice from a column cell holding an array. The columnname and (0-relative) rownr indicate the table cell. The slice to get is defined by the blc, trc, and optional inc arguments (blc = bottom-left corner, trc=top-right corner, inc=stride). Not all axes have to be filled in for blc, trc, and inc. Missing axes default to begin, end, and 1. A negative blc or trc defaults to begin or end. Note that trc is inclusive (unlike python indexing). """
