Table guide

This package can be installed in every node project as well as react-native-cli and expo-cli. The simple project comes from a personal need. Hope this will be useful!

This package allows you to use simple tables easily.

Installation

It's very easy to download, just run the following command: npm install node_tables

Simple demo (javascript)

The javascript code is very simple, first you need to import the package by using:

import Tables from "node_tables";

Then create the object Table:

let table = new Table(arg1,arg2,arg3,arg4,arg5);

Below there is the full table where you can understand the function of the five arguments.

|Name|Function| |---|---| |arg1|Number of rows| |arg2|Number of columns| |arg3|It's a boolean variable that allows you to use labels for columns and rows.| |arg4|If the third argument is true, you have to pass the array of labels (row names)| |arg5|If the third argument is true, you have to pass the array of labels (columns names)|

Tip

You will be able to point to a cell by passing the row number, and the column number or simply by the row's name,and the column's name.

Then, create the 2D array of data:

const values = [
    [64,59,56,51], [65, 60, 61, 55], [67,65,62,63], [67,65.6,62.7,63], [67,65,'k',63],
]

Now you can fill the table by passing the previous 2D array (this is an async function).

table.fill(values).then(() => {table.print(); console.log('The value selected is: ',table.getValue(1, 1))});

Warning

The indexes (row and column) start from 1 and not from 0 as usual in arrays (this way should be easier to read).

All the methods

Down below there the full table that shows you all the available methods.

|Name|Function| |---|---| |fill(array)|Fill the table by passing the 2D data array.| |getCell(row, column)| It returns the cell object at those indexes (you can also pass the row's name or the column's name).| |getValue(row, column)|It returns the cell value at those indexes (you can also pass the row's name or the column's name).| |set(val, row, column)|It overrides the value of a cell with a new one (you can also pass the row's name or the column's name). | |indexOf(val, allowStringConversion)|It returns an array containing all the row indexes and column indexes when it finds your value. In order to be able to search for an integer by passing a string with the same value (or the other way around) you have to pass a boolean as the second argument.| |print()|It is used mainly for debug and it prints the table in the console.|
