1繪制直線
canvas.drawLine(0 + marginLeft, marginTop, 0 + marginLeft, height - marginTop, paint);
2在表格中繪制文字劇中，主要邏輯在于表格x軸坐標(biāo)+(表格-文字寬度)/2
paint.setStrokeWidth(1);
paint.setTypeface(Typeface.DEFAULT);
paint.setTextSize(textSize);
//繪制word
float wordWidth = paint.measureText(word);
float wordX = (hundredMargin - wordWidth) / 2;
float baseLineY = sinagelRowHeight / 2 + Math.abs(paint.ascent() + paint.descent()) / 2 + marginTop;
canvas.drawText(word, wordX + thirtyTwoMargin + marginLeft, baseLineY, paint);
