Row selection

The select extension let you select rows (or cells). When you do so, only the selected rows are exported

from itables import init_notebook_mode, show

init_notebook_mode()

Loading ITables v2.2.4 from the init_notebook_mode cell... (need help?)

Tip

It is possible to get the updated selected_rows back in Python but for this you will have to use, instead of show, either

• the ITable Jupyter Widget

• the interactive_table Streamlit component

• or DT in a Shiny app.

Tip

The select option accept multiple values, as documented here:

• select=True or select="os" let you select using single click, shift-click and ctrl-click

• select="single" let you select a single row

• select="multi" for single click selection of multiple rows, select="multi+shift", …

With select={"style": "os", "items": "cell"} you can let the user select specific cells, however cell selection is not taken into account when exporting the data.
