TableDataView
A Visual Studio Code extension that displays CSV, TSV, and other tabular text files as interactive tables with graph support.
Features
Table View
- Open any
.csv, .tsv, .txt, or .dat file as an interactive table
- Automatic delimiter detection (comma, tab, semicolon, pipe, space)
- Automatic header detection — if the first row contains non-numeric values, it is used as column headers
- Virtual scrolling for large files with no row limit
- All columns are left-aligned
Column Selection
- The first column (column 0) is always selected and pinned — it stays fixed while scrolling horizontally
- Click a column header or any cell to select that column (column 0 remains selected)
- Shift+click to select a range of columns
- Ctrl/Cmd+click to toggle individual columns in a multi-selection
Navigation
- Top button: jump to the first row
- Bottom button: jump to the last row
Graph View
- Select one or more columns, then click Show Graph or right-click and choose Show graph
- If column 0 is included in the selection alongside other columns, it is used as the X-axis
- Supports line and bar chart types (toggle button in the graph panel)
- Adjustable line width
- Click on the graph to show a crosshair and highlight the corresponding row in the table
- Decimation: large datasets (>2,000 points) are automatically downsampled for smooth rendering
Usage
- In the Explorer or Editor, right-click a supported file
- Select TableDataView: table view
- The file opens in a new panel as a table
