+- Update to 0.1.29
+  * Add read-only
+  * Only fix row and column count when not read-only
+  * Only update visible cells in read-only mode. Dramatically
+    speeds up viewing large datasets
+  * Optimize copy-cut-delete (still slow)
+  * Only update visible cells for writable tables
+  * Fix a visualization issue when scrolling past the last row
+  * Catch IndexError when copying
+  * Fix RuntimeError when pasting cells
+- test with rudimentary example.py
+- adjust requirements
