python-docx 垂直居中以及行高失效问题

python-docx 的垂直居中问题以及行高失效问题

我翻了下源码发现这个包暂时没有办法全局Table设置垂直居中，只找到了cell垂直居中的方法。所以我修改了行内的方法在写之前先设置样式。行高失效的话是因为这个模块的缺陷，导致直接对新的row赋值高度失效，所以就只能使用

self.table.rows[当前行索引].height

来设置行高。下边是我对table相关操作简单封装的一个模块。

封装之后如下

class CreateTable:
    """
        table 操作
    """

    def __init__(self, rows, cols, width_list, height, document, font_size=10, font_color=(0, 0, 0), floats='LEFT',

        """

• PS : 其中

  xu.vertical_alignment = WD_CELL_VERTICAL_ALIGNMENT.CENTER

  中

  xu

  为当前需要填充的cell，

  vertical_alignment = WD_CELL_VERTICAL_ALIGNMENT.CENTER

  即为设置垂直居中的方法。
