Installation

go get github.com/rapidfort/table

Quick Start

package main

import (
    "fmt"
    "github.com/rapidfort/table"
)

func main() {
    // Create a table
    tbl := table.RapidFortTable([]string{"Name", "Age", "City"})
    
    // Add rows
    tbl.AddRow([]string{"Alice", "30", "New York"})
    tbl.AddRow([]string{"Bob", "25", "San Francisco"})
    
    // Add description to a row
    tbl.AddDescription(0, "Special customer discount applied")
    
    // Render and print
    fmt.Println(tbl.Render())
}

This produces:

┌───────┬─────┬───────────────┐
│ Name  │ Age │ City          │
├───────┼─────┼───────────────┤
│ Alice │ 30  │ New York      │
│       ├─────┴───────────────┤
│       │   • Special         │
│       │     customer        │
│       │     discount        │
│       │     applied         │
├───────┼─────┬───────────────┤
│ Bob   │ 25  │ San Francisco │
└───────┴─────┴───────────────┘

Advanced Usage

Header Styling

// Highlight specific headers
tbl.SetHighlightedHeaders([]int{0, 2}) // Highlights columns 0 and 2

// Always highlight all headers (bold style)
tbl.SetHeaderHighlighting(true)

// Add/remove highlighting dynamically
tbl.AddHighlightedHeader(1)
tbl.ClearHighlightedHeaders()

Border and Style Control

// Enable dim borders (light gray)
tbl.SetDimBorder(true)

// Remove borders completely
tbl.SetBorderless(true)

// Automatic terminal width detection (default)
tbl.SetConsoleWidth(80) // Manual override

Column Formatting

// Set column alignment
tbl.SetAlignment(0, "left")   // Column 0: left-aligned
tbl.SetAlignment(1, "right")  // Column 1: right-aligned
tbl.SetAlignment(2, "center") // Column 2: center-aligned

// Set maximum column widths
tbl.SetMaxWidth(1, 20)        // Column 1 max width: 20 chars

// Enable width filling
tbl.SetFillWidth(true)        // Expand to fill terminal width

Table Groups

When multiple tables need consistent column widths:

group := table.NewGroup()

// Create tables
table1 := table.RapidFortTable(headers)
table2 := table.RapidFortTable(headers)

// Add to group
group.Add(table1)
group.Add(table2)

// Sync column widths across all tables
group.SyncColumnWidths()

// Render tables with consistent widths
fmt.Println(table1.Render())
fmt.Println(table2.Render())

Rich Descriptions

// Add description with title
tbl.AddDescriptionWithTitle(rowIndex, "Advisory", "High demand item, consider restocking")

// Add simple description
tbl.AddDescription(rowIndex, "This item is currently on backorder")

// Multi-line descriptions are automatically wrapped
tbl.AddDescription(rowIndex, "This is a long description that will wrap across multiple lines based on the available space in the table")

Examples

Complete Feature Showcase

// Create table with all features
tbl := table.RapidFortTable([]string{"ID", "Product", "Stock", "Status"})

// Configure styling
tbl.SetDimBorder(true)
tbl.SetHighlightedHeaders([]int{1, 3})
tbl.SetAlignment(2, "right")
tbl.SetMaxWidth(1, 15)

// Add data
tbl.AddRow([]string{"001", "Wireless Mouse", "125", "Active"})
tbl.AddRow([]string{"002", "USB-C Hub Pro", "25", "Low Stock"})
tbl.AddRow([]string{"003", "Mechanical Keyboard", "50", "Active"})

// Add descriptions
tbl.AddDescriptionWithTitle(1, "Alert", "Reorder soon to avoid stockout")
tbl.AddDescription(2, "Popular item, high demand expected")

fmt.Println(tbl.Render())

Borderless Table

tbl := table.RapidFortTable([]string{"Name", "Value"})
tbl.SetBorderless(true)
tbl.AddRow([]string{"Setting 1", "Enabled"})
tbl.AddRow([]string{"Setting 2", "Disabled"})
fmt.Println(tbl.Render())
