## Description
Several changes made to enhance the table performance:
- Batch updates of meta properties to limit the number of rerenders
- Removed expensive comparator operations.
- Memoised components which are not susceptible to updates.
- Table filter code optimisation to limit the number of times setState
is triggered.
Fixes#20910
## Description
This PR upgrades Prettier to v2 + enforces TypeScript’s [`import
type`](https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-8.html#type-only-imports-and-export)
syntax where applicable. It’s submitted as a separate PR so we can merge
it easily.
As a part of this PR, we reformat the codebase heavily:
- add `import type` everywhere where it’s required, and
- re-format the code to account for Prettier 2’s breaking changes:
https://prettier.io/blog/2020/03/21/2.0.0.html#breaking-changes
This PR is submitted against `release` to make sure all new code by team
members will adhere to new formatting standards, and we’ll have fewer
conflicts when merging `bundle-optimizations` into `release`. (I’ll
merge `release` back into `bundle-optimizations` once this PR is
merged.)
### Why is this needed?
This PR is needed because, for the Lodash optimization from
7cbb12af88,
we need to use `import type`. Otherwise, `babel-plugin-lodash` complains
that `LoDashStatic` is not a lodash function.
However, just using `import type` in the current codebase will give you
this:
<img width="962" alt="Screenshot 2023-03-08 at 17 45 59"
src="https://user-images.githubusercontent.com/2953267/223775744-407afa0c-e8b9-44a1-90f9-b879348da57f.png">
That’s because Prettier 1 can’t parse `import type` at all. To parse it,
we need to upgrade to Prettier 2.
### Why enforce `import type`?
Apart from just enabling `import type` support, this PR enforces
specifying `import type` everywhere it’s needed. (Developers will get
immediate TypeScript and ESLint errors when they forget to do so.)
I’m doing this because I believe `import type` improves DX and makes
refactorings easier.
Let’s say you had a few imports like below. Can you tell which of these
imports will increase the bundle size? (Tip: it’s not all of them!)
```ts
// app/client/src/workers/Linting/utils.ts
import { Position } from "codemirror";
import { LintError as JSHintError, LintOptions } from "jshint";
import { get, isEmpty, isNumber, keys, last, set } from "lodash";
```
It’s pretty hard, right?
What about now?
```ts
// app/client/src/workers/Linting/utils.ts
import type { Position } from "codemirror";
import type { LintError as JSHintError, LintOptions } from "jshint";
import { get, isEmpty, isNumber, keys, last, set } from "lodash";
```
Now, it’s clear that only `lodash` will be bundled.
This helps developers to see which imports are problematic, but it
_also_ helps with refactorings. Now, if you want to see where
`codemirror` is bundled, you can just grep for `import \{.*\} from
"codemirror"` – and you won’t get any type-only imports.
This also helps (some) bundlers. Upon transpiling, TypeScript erases
type-only imports completely. In some environment (not ours), this makes
the bundle smaller, as the bundler doesn’t need to bundle type-only
imports anymore.
## Type of change
- Chore (housekeeping or task changes that don't impact user perception)
## How Has This Been Tested?
This was tested to not break the build.

## Description
This PR implements the following changes:
- Move the drag events from the Parent component's useEffect to the
`HeaderCell` component.
- Refactored the code. Inside the table component, we refactored the
code such that when SSP is disabled the component uses `StaticTable` and
when SSP enabled then we use `VirtualTable`.
- It also includes the fix for the following issue. Whenever the user
has a scroll to the bottom of the page, on clicking of add new button it
is expected that the scroll should move to the top but it wasn't
happening.
> Add a TL;DR when description is extra long (helps content team)
Fixes#20858
> if no issue exists, please create an issue and ask the maintainers
about this first
## Type of change
- Bug fix (non-breaking change which fixes an issue)
## How Has This Been Tested?
- Manual
- Test cases:
- Column name should appear on update from the property pane
- reorder whenever SSP is enabled
- On column re-size
- When a col is frozen
- When a col is unfrozen
- When all the headers or one of them is removed
- When sorted also should work
- Enable multi-row selection
- When in preview mode and back and forth(Check the above cases)
- When in Deployed mode
- Dragging of columns from the column header should work as expected
both in Deploy and Published mode.
- Cypress

**PRD**:
https://www.notion.so/appsmith/Ability-to-freeze-columns-dd118f7ed2e14e008ee305056b79874a?d=300f4968889244da9f737e1bfd8c06dc#2ddaf28e10a0475cb69f1af77b938d0b
This PR adds the following features to the table widget:
- Freeze the columns to the left or right of the table.(Both canvas and
page view mode).
- Unfreeze the frozen columns. (Both canvas and page view mode).
- Columns that are left frozen, will get unfrozen at a position after
the last left frozen column. (Both canvas and page view mode).
- Columns that are right frozen, will get unfrozen at a position before
the first right frozen column. (Both canvas and page view mode).
- Column order can be persisted in the Page view mode.
- Users can also unfreeze the columns that are frozen by the developers.
- Columns that are frozen cannot be reordered(Both canvas and page view
mode)
- **Property pane changes (Columns property)**:
- If the column is frozen to the left then that column should appear at
top of the list.
- If the column is frozen to the right then that column should appear at
the bottom of the list.
- The columns that are frozen cannot be moved or re-ordered in the list.
They remain fixed in their position.
- In-Page mode, If there is a change in frozen or unfrozen columns in
multiple tables then the order of columns and frozen and unfrozen
columns should get persisted on refresh i.e. changes should get
persisted across refreshes.
