Duowei Table

Local, spreadsheet-style structured data for Obsidian. Records, fields, views, and settings live in plain-text JSON .duowei files inside your vault, so they can be read, diffed, synchronized, and backed up with ordinary tools.

The Community Edition includes the complete local table engine, 22 field types, seven view types, imports and exports, Markdown integration, and backup recovery. It requires no account, license key, trial, payment, or cloud service.

An optional enhanced edition, Duowei Table Pro, is distributed separately. It is never required to use the Community Edition.

Interface language: the plugin interface, commands, and settings are currently in Simplified Chinese. This English README is a translated usage guide; it does not indicate that the interface itself has been localized.

Usage

Standalone tables

1. Open the Command Palette.
2. Run 创建空白多维表格 (Create blank multidimensional table).
3. The plugin creates and opens a .duowei file. New tables are stored in the 多维表格 folder by default.
4. Add fields with the + button in the header, then add records or configure filters, groups, sorting, colors, and views from the toolbar.

Design principles:

• A row is a record; it does not have to correspond to a Markdown file.
• A column is a field that can be managed directly inside the table.
• Cell values, field definitions, and view settings live in the .duowei file.
• Markdown binding, frontmatter synchronization, and Bases migration are optional capabilities rather than prerequisites.

Example tables are available in examples/content-operations. Copy them into a vault and open them after enabling the plugin.

Imports and vault data sources

• 从 Base 创建多维表格 (Create a table from Base) converts a selected .base file into a standalone table.
• 从当前 Base 创建多维表格 (Create a table from the current Base) converts the Base currently open in Obsidian.
• 从文件夹创建多维表格 (Create a table from a folder) can create either an editable imported table or a live read-only index of notes, images, documents, media, or all files in a vault scope.
• CSV/TSV import and export are available from the table menus.
• 快速添加记录到多维表格 (Quick-add a record) appends a record without opening the target table.

Editable folder imports can bind records to Markdown files and synchronize configured fields with frontmatter. Live vault indexes keep source files as the single source of truth and are intentionally read-only inside the table.

Bases-compatible layout

1. Enable Obsidian's core Bases plugin.
2. Enable Duowei Table.
3. Create or open a .base file.
4. Select 多维表格 (Duowei Table) from the view/layout menu.

The compatibility layout uses Bases and Markdown/frontmatter as its data source. Use one of the Base conversion commands when you want an independent .duowei file instead.

Embedding tables in notes

Embed a table or a named view with an Obsidian wikilink:

![[多维表格/项目管理.duowei]]
![[多维表格/项目管理.duowei#表格]]

Use a duowei code block to select a view, record limit, and fields:

```duowei
path: 多维表格/项目管理.duowei
view: 表格
limit: 10
fields: 标题, 状态, 截止日期
```

Embedded tables are read-only mini views that follow the target view's filters and sorting. In the Markdown editor, run 插入多维表格图表引用 (Insert a Duowei Table chart reference) to embed an individual dashboard chart.

Keyboard operations

• Ctrl/Cmd+C and Ctrl/Cmd+V: copy or paste a cell/range/TSV matrix
• Delete or Backspace: clear editable cells
• Tab and Shift+Tab: move between cells
• Ctrl/Cmd+H: find and replace
• Ctrl/Cmd+Arrow: jump to a data boundary
• Home and End: jump to the start or end of a row
• Hold Shift with navigation shortcuts to extend the selection

Editions and compatibility

The Community Edition is free to install and use. Every feature documented here works without an account, license key, trial, or payment and is licensed under the GNU General Public License v3.0.

The separately distributed Duowei Table Pro primarily adds AI fields, external calendar/task synchronization, and favorites synchronization. Formula, relation, lookup, rollup, long-text, calendar, timeline, form, and dashboard features are already part of the current Community Edition.

Both editions use the .duowei extension and schemaVersion: 1 data format. Files created by the Community Edition can be opened directly in Pro. Keep a backup before editing a file that contains Pro-only configuration in the Community Edition.

Do not enable both editions at the same time. They register the same file extension and view types.

Data and privacy

• .duowei files are plain-text JSON stored inside your vault.
• No account or cloud database is required.
• The Community Edition contains no analytics, telemetry, crash reporting, user identifiers, account service, or background vault upload logic.
• AI requests, external calendar/task synchronization, and favorites synchronization are not implemented in the Community Edition.
• External modifications are detected before saving; the plugin creates a conflict snapshot instead of silently overwriting the file.
• Automatic backups use the .duoweibak extension and are stored in 多维表格备份/{{folder}} by default. The default minimum interval is 10 minutes, with 12 snapshots retained per table.
• Tables, backups, and dropped attachments stay inside the vault by default. On desktop, CSV/TSV export writes outside the vault only after you explicitly choose a destination.

Network use

Core features such as editing, formulas, filtering, views, and local backups work offline. The plugin contains no telemetry endpoint, account synchronization service, or background logic that uploads vault data.

Normal network access may still occur when you deliberately open an external link, display a remote image URL, copy a chart containing remote resources as an image, use Obsidian's official update mechanism, or open an external website linked from this document. Otherwise, the local table workflow does not depend on an external service.

Installation

Requirements:

• Obsidian 1.10.0 or later
