cli tableau
Horizontal Tables
var Table = require('cli-tableau');
var table = new Table({
head: ['TH 1 label', 'TH 2 label'],
colWidths: [100, 200],
borders: false
});
table.push(
['First value', 'Second value'],
['First value', 'Second value']
);
console.log(table.toString());
Vertical Tables
var Table = require('cli-tableau');
var table = new Table();
table.push(
{ 'Some key': 'Some value' },
{ 'Another key': 'Another value' }
);
console.log(table.toString());
Cross Tables
Cross tables are very similar to vertical tables, with two key differences:
- They require a
head
setting when instantiated that has an empty string as the first header - The individual rows take the general form of { "Header": ["Row", "Values"] }
var Table = require('cli-tableau');
var table = new Table({ head: ["", "Top Header 1", "Top Header 2"] });
table.push(
{ 'Left Header 1': ['Value Row 1 Col 1', 'Value Row 1 Col 2'] },
{ 'Left Header 2': ['Value Row 2 Col 1', 'Value Row 2 Col 2'] }
);
console.log(table.toString());
Custom styles
The chars
property controls how the table is drawn:
var table = new Table({
chars: {
'top': '═' , 'top-mid': '╤' , 'top-left': '╔' , 'top-right': '╗',
'bottom': '═' , 'bottom-mid': '╧' , 'bottom-left': '╚' , 'bottom-right': '╝',
'left': '║' , 'left-mid': '╟' , 'mid': '─' , 'mid-mid': '┼',
'right': '║' , 'right-mid': '╢' , 'middle': '│'
}
});
table.push(
['foo', 'bar', 'baz'],
['frob', 'bar', 'quuz']
);
console.log(table.toString());
// Outputs:
//
//╔══════╤═════╤══════╗
//║ foo │ bar │ baz ║
//╟──────┼─────┼──────╢
//║ frob │ bar │ quuz ║
//╚══════╧═════╧══════╝
Empty decoration lines will be skipped, to avoid vertical separator rows just set the 'mid', 'left-mid', 'mid-mid', 'right-mid' to the empty string:
var table = new Table({ chars: {'mid': '', 'left-mid': '', 'mid-mid': '', 'right-mid': ''} });
table.push(
['foo', 'bar', 'baz'],
['frobnicate', 'bar', 'quuz']
);
console.log(table.toString());
// Outputs: (note the lack of the horizontal line between rows)
//┌────────────┬─────┬──────┐
//│ foo │ bar │ baz │
//│ frobnicate │ bar │ quuz │
//└────────────┴─────┴──────┘
By setting all chars to empty with the exception of 'middle' being set to a single space and by setting padding to zero, it's possible to get the most compact layout with no decorations:
var table = new Table({
chars: {
'top': '' , 'top-mid': '' , 'top-left': '' , 'top-right': '',
'bottom': '' , 'bottom-mid': '' , 'bottom-left': '' , 'bottom-right': '',
'left': '' , 'left-mid': '' , 'mid': '' , 'mid-mid': '',
'right': '' , 'right-mid': '' , 'middle': ' '
},
style: { 'padding-left': 0, 'padding-right': 0 }
});
table.push(
['foo', 'bar', 'baz'],
['frobnicate', 'bar', 'quuz']
);
console.log(table.toString());
// Outputs:
//foo bar baz
//frobnicate bar quuz
