WIP, when complete, will close #252

…esults

Expression is not evaluated correctly, results can be queried but are not yet displayed in the table

…ric plots

This will allow data table results to be assembled

Still need to implement rendering of data table query results on the front end

…data table

Need to fix get_data_table_subs tree walking algorithm and rendering of units in data table for calculated columns

Also, fix parsing of assign_plus_query for data tables

…lculation

Also, don't parse column expression for output columns

…ehavior

…celing behavior"

This reverts commit dc7ba99.

Prevents changes in behavior to existing notebooks. Tests for math cell types are skipped for now.

test assign and computed with and without units, test adding and deleting rows and columns, test non number truncation of column

firefox 127 is needed for set symmetricDifference

Will be adding other functions to this file

Prevents floating point issues for fractional step sizes

…polation

Need to implement interpolation and polyfit capabilities in Python

Still need to add the poly order widget to the datatable

Currently there are issues with the DOM updating properly after the import

Might make more sense to use a constructor to create a new datatable cell rather than try to change the current one.

Still need to fix initial refresh problem by converting selectAndLoadSpreadsheetFile to a promise

Need to wait for sheetjs to be loaded before attempting to fill out table

…r loading

…nput and error handling

Need to convert units to a human readable format

…r pdf export

Also, rename the original table cell to selector table cell

Needed for update webkit version
