# Easy table
Nice utility for rendering text tables with javascript.
## Usage
```javascript
var Table = require('easy-table')
var data = [
{ id: 123123, desc: 'Something awesome', price: 1000.00 },
{ id: 245452, desc: 'Very interesting book', price: 11.45},
{ id: 232323, desc: 'Yet another product', price: 555.55 }
]
var t = new Table
data.forEach(function(product) {
t.cell('Product Id', product.id)
t.cell('Description', product.desc)
t.cell('Price, USD', product.price, Table.number(2))
t.newRow()
})
console.log(t.toString())
```
The script above will render:
```
Product Id Description Price, USD
---------- --------------------- ----------
123123 Something awesome 1000.00
245452 Very interesting book 11.45
232323 Yet another product 555.55
```
`t.printTransposed()` returns
```
Product Id : 245452 : 232323 : 123123
Description : Very interesting book : Yet another product : Something awesome
Price, USD : 11.45 : 555.55 : 1000.00
```
`t.print()` shows just rows you pushed and nothing more
```
123123 Something awesome 1000.00
245452 Very interesting book 11.45
232323 Yet another product 555.55
```
### How it works
The full signature of `.cell()` is:
```javascript
t.cell(column, value, printer)
```
Rendering occures in two phases. At the first phase `printer`
is called to get the minimal width required to fit the cell content.
At the second phase `printer` is called again with
additional `width` parameter to get actual string to render.
For example, here is how currency printer might be defined
``` javascript
function currency(val, width) {
var str = val.toFixed(2)
return width ? Table.padLeft(str, width) : str
}
```
### Table.print()
When you already have an array, explicit table instantiation and iteration
becomes an overhead. For such cases it is convenient to use `Table.print()`.
``` javascript
console.log(Table.print(data))
```
```
id desc price
------ --------------------- ------
123123 Something awesome 1000
245452 Very interesting book 11.45
232323 Yet another product 555.55
```
It is possible to pass some options
``` javascript
Table.print(data, {
desc: {name: 'description'}
price: {printer: Table.number(2)}
})
```
```
id description price
------ --------------------- -------
123123 Something awesome 1000.00
245452 Very interesting book 11.45
232323 Yet another product 555.55
```
or have a full control over rendering
``` javascript
Table.print(data, function(item, cell) {
cell('Product id', item.id)
cell('Price, USD', item.price)
}, function(table) {
return table.print()
})
```
`Table.print()` also accepts objects
``` javascript
Table.print(data[0])
```
```
id : 123123
desc : Something awesome
price : 1000
```
### Sorting
You can sort a table by calling `.sort()`, and optionally passing in a list of
column names to sort on (by default uses all columns), or a custom comparator
function. It is also possible to specify the sort order. For example:
``` javascript
t.sort(['Price, USD|des']) // will sort in descending order
t.sort(['Price, USD|asc']) // will sort in ascending order
t.sort(['Price, USD']) // sorts in ascending order by default
```
### Totaling
Easy table can help to calculate and render totals:
``` javascript
t.total('Price, USD')
```
```
Product Id Description Price, USD
---------- --------------------- ----------
245452 Very interesting book 11.45
232323 Yet another product 555.55
123123 Something awesome 1000.00
---------- --------------------- ----------
1567.00
```
Here is a more elaborate example
```javascript
t.total('Price, USD', {
printer: Table.aggr.printer('Avg: ', currency),
reduce: Table.aggr.avg,
init: 0
})
// or alternatively
t.total('Price, USD', {
printer: function(val, width) {
return padLeft('Avg: ' + currency(val), width)
},
reduce: function(acc, val, idx, len) {
acc = acc + val
return idx + 1 == len ? acc/len : acc
}
})
```
```
Product Id Description Price, USD
---------- --------------------- -----------
245452 Very interesting book 11.45
232323 Yet another product 555.55
123123 Something awesome 1000.00
---------- --------------------- -----------
Avg: 522.33
