[v1.0.5-pre] How to disable headers?

[zx8]

I'm trying to match my v0.0.5 configuration using the latest commit 88e7330 so I can prove feedback before the release. I've managed to discover the majority of settings, but the two I can't seem to find the equivalents of are:

table.SetHeaderLine(false)
table.SetTablePadding("  ")

---

Also, another suggestion (to save me raising a separate issue) since tw.BorderNone already exists as a convenient helper, could you also add:

tw.LinesNone := tw.Lines{
  ShowTop:        tw.Off,
  ShowBottom:     tw.Off,
  ShowHeaderLine: tw.Off,
  ShowFooterLine: tw.Off,
}

and

tw.SeparatorsNone := tw.Separators{
  ShowHeader:     tw.Off,
  ShowFooter:     tw.Off,
  BetweenRows:    tw.Off,
  BetweenColumns: tw.Off,
}

Hi @zx8 ,

Will help you add tablewriter.WithPadding to help you simplify global padding forever for fine grain padding you may want to see

tablewriter/tests/basic_test.go

Lines 530 to 580 in 0fd7b11

	func TestTableWithCustomPadding(t *testing.T) {
	data := [][]string{
	{"Regular", "regular line", "1"},
	{"Thick", "particularly thick line", "2"},
	{"Double", "double line", "3"},
	}
	c := tablewriter.Config{
	Header: tw.CellConfig{
	Formatting: tw.CellFormatting{
	Alignment: tw.AlignCenter,
	AutoFormat: true,
	},
	Padding: tw.CellPadding{
	Global: tw.Padding{Left: " ", Right: " ", Top: "^", Bottom: "^"},
	},
	},
	Row: tw.CellConfig{
	Formatting: tw.CellFormatting{
	Alignment: tw.AlignCenter,
	},
	Padding: tw.CellPadding{
	Global: tw.Padding{Left: "L", Right: "R", Top: "T", Bottom: "B"},
	},
	},
	Footer: tw.CellConfig{
	Formatting: tw.CellFormatting{
	Alignment: tw.AlignCenter,
	AutoFormat: true,
	},
	Padding: tw.CellPadding{
	Global: tw.Padding{Left: "*", Right: "*", Top: "", Bottom: ""},
	},
	},
	}
	var buf bytes.Buffer
	table := tablewriter.NewTable(&buf, tablewriter.WithConfig(c))
	table.Header([]string{"Name", "Age", "City"})
	table.Bulk(data)
	table.Render()
	expected := `
	┌─────────┬─────────────────────────┬──────┐
	│ ^^^^^^^ │ ^^^^^^^^^^^^^^^^^^^^^^^ │ ^^^^ │
	│ NAME │ AGE │ CITY │
	│ ^^^^^^^ │ ^^^^^^^^^^^^^^^^^^^^^^^ │ ^^^^ │

Hope this helps ?

Sorry, I wanted to disable the header entirely as well, if that's possible? So rather than:

┌───────┬────────┬──────────┐
│*NAME##│**AGE###│***CITY###│
├───────┼────────┼──────────┤
│*Alice#│*25 yrs#│*New York#│
│*Bob###│*30 yrs#│*Boston###│
└───────┴────────┴──────────┘

I wanted:

┌───────┬────────┬──────────┐
│*Alice#│*25 yrs#│*New York#│
│*Bob###│*30 yrs#│*Boston###│
└───────┴────────┴──────────┘

[olekukonko]

just comment out the header

package main

import (
	"fmt"
	"github.com/olekukonko/tablewriter"
	"github.com/olekukonko/tablewriter/tw"
	"os"
)

type Age int

func (a Age) String() string {
	return fmt.Sprintf("%d yrs", a)
}

func main() {
	data := [][]any{
		{"Name", "Age", "City"},
		{"Alice", Age(25), "New York"},
		{"Bob", Age(30), "Boston"},
	}

	table := tablewriter.NewTable(
		os.Stdout,
		tablewriter.WithPadding(tw.Padding{
			Left:   "*",
			Right:  "#",
			Top:    "",
			Bottom: "",
		}),
	)

	/// table.Header(data[0])
	table.Bulk(data[1:])
	table.Render()
}

┌───────┬────────┬──────────┐
│*Alice#│*25 yrs#│*New York#│
│*Bob###│*30 yrs#│*Boston###│
└───────┴────────┴──────────┘

However, if I understand your use case correctly, I may be able to add a configuration ... help me out.

Sure, I am loading a CSV like:

r := csv.NewReader(os.Stdin)
table, err := tablewriter.NewCSVReader(os.Stdout, r, true)
if err != nil {
    return err
}
table.Render()

The input data has a header, but I want to skip it when rendering the table.

[olekukonko]

Understandable will add support for this so you can do

package main

import (
	"encoding/csv"
	"github.com/olekukonko/ll"
	"github.com/olekukonko/tablewriter"
	"github.com/olekukonko/tablewriter/tw"
	"os"
	"strings"
)

const csvTestData = `Name,Department,Salary
Alice,Engineering,120000
Bob,Marketing,85000
Charlie,Engineering,135000
Diana,HR,70000
`

func main() {
	r := csv.NewReader(strings.NewReader(csvTestData))
	table, err := tablewriter.NewCSVReader(os.Stdout, r, true,
		tablewriter.WithDebug(true),
		tablewriter.WithHeaderControl(tw.Control{Hide: tw.On}),
	)

	if err != nil {
		ll.Fatal(err)
	}

	table.Render()
}

┌─────────┬─────────────┬────────┐
│ Alice   │ Engineering │ 120000 │
