How to text display in the same cell without color in jspdf

Question

• How to displays different colors within a cell just like in the
  picture.
• The table is generated with jspdf-autotable.
• I didn't find a related method in the docs.

Here is my code. `

doc.autoTable({
    startY: contentHeight,
    html: `#${key}`,
    theme: 'grid',
    styles: {
      font: 'SourceHanSansCN',
      fontStyle: 'normal'
    },
    columnStyles: {
      0: {cellWidth: 'wrap'}
    },
    pageBreak: 'auto'
