Data tables v1

[ddimaria]

Main branch for merging data table related work.

Closes https://github.com/quadratichq/quadratic/issues/1412

Data Tables (Rust and quadraticCore)

• [x] Convert sheet.code_runs into sheet.data_tables, moving code_runs inside of data tables
• [x] CSV and Parquet Imports become another data_table sub type instead of being on the grid
• [x] Column metadata (name, order, hidden)
  • [x] Apply First Row as Header
  • [x] Apply Default Headers
  • [x] New Raw Data Table
  • [x] Set Header At
  • [x] Set Header Display At
• [x] Table metadata (name, readonly)
• [x] Edit data table in place (readonly=false)
• [x] Flatten Table (data table to grid)
• [x] Grid to data table
• [x] Sort data tables
• [x] Table names should always be unique
• [x] Ensure table name is unique after user edit
• [x] Code table to data table (only for Code Tables)
• [ ] Ensure column names are always unique within a table
• [ ] Toggle show alternating colors
• [ ] Toggle showing table column headers
• [ ] Rename column headers (only for Data Tables? We may want to allow code table columns to be renamed if first_row_as_header == false)
• [ ] Filter data tables
• [ ] Copy and paste data tables

UI (TS)

• [x] Show table name on cursor hover or when the cursor is inside the table
• [x] table name scales w/app
• [x] Render Table headings w/styles
• [x] rename table
• [x] Rename column headers
• [x] Table headers should not have opacity. Grid lines overlap content.
• [x] Table column sort dialog
• [x] Sort table dialog
• [x] Spill error rework
• [ ] improve connection icons when displayed in table name
• [ ] Selecting entire table
• [ ] Selecting table column
• [ ] Formatting for table
• [ ] Formatting for table cells
• [ ] Formatting for table headings
• [ ] Formatting for table columns
• [ ] maybe change text clipping rules for tables?
• [ ] move data table by dragging on table name?
• [ ] should not be able to autocomplete table column headers
• [ ] Selecting multiple tables, and showing their borders selected. Feels like it should work like Figma with multi frame selections

Quadratic Code Additions

• [ ] A1 support of tables
• [ ] JS API to include data table name
• [ ] Python API to include data table name

Bugs

• [ ] Entering data via down arrow causes a weird state (type text, press down arrow; type text, press down arrow, continue until you the grid ends up losing focus)
• [x] Cell error popup no longer working
• [ ] Bug with rename column name

Reach Goals

• [ ] group table (in sort)

Documentation and Test Files

• [ ] Change all example files to use Sheet1 instead of Sheet 1
