export default {
  numberFormatter: (num, digits) => {
    const si = [

      { value: 1E15, symbol: 'P' },
      { value: 1E12, symbol: 'T' },

      { value: 1E6, symbol: 'M' },
      { value: 1E3, symbol: 'k' }
    ]
    for (let i = 0; i < si.length; i++) {
      if (num >= si[i].value) {
        return (num / si[i].value).toFixed(digits).replace(/\.0+$|(\.[0-9]*[1-9])0+$/, '$1') + si[i].symbol
      }
    }
    return num.toString()
  },

  tranForm(data) {
