Summary
HiTable is a powerful browser extension designed to simplify your data analysis tasks. It allows you to perform instant, in-place calculations on HTML tables directly within your browser.

It's perfect for quick data analysis, auditing data, or just exploring numbers on web pages.
How to Use
First, after installing this extension, you need to pin it to the browser's toolbar. By default, this extension is not activated, and the icon in the toolbar is displayed in gray. When you need to use this extension for table data calculation, click the icon in the toolbar to activate the extension, at which point the icon will be displayed as an icon with a green frame.
Please open a page that contains a data table, such as: https://en.wikipedia.org/wiki/Economy_of_the_United_States#Data
Once activated, you can select a rectangular area in the table by pressing the left mouse button and dragging. Release the mouse to end the selection, at which point a floating layer will pop up outside the selected area, which will perform various statistics on the rows and columns of the selected area on four sides. The clockwise left side of these four sides shows the statistical algorithm being used on each side.
You can cancel the selection by clicking on a cell outside the selected area or pressing the Esc
key. When the Shift
key is pressed, dragging the selection in the first row or first column will select multiple entire columns or rows; if you click on the top left cell of the table (i.e., the first cell of the first row) while pressing the Shift
key, the entire table will be selected.
Clicking on the four corners of the floating layer can switch between multiple statistical algorithms. Pressing CTRL-C
(or Meta-C
on a Mac) can copy the selected area, and the copied content can be pasted into tools like Excel, Numbers, etc. for more complex processing. If you press CTRL-C
(or Meta-C
on a Mac) twice in quick succession, you can copy all the data including the floating layer and the selected area.
