Fill cell area Needed table cells to be links  Only link content was clickable, but area around it not That is how I expended the link area to fit the table cell How it was...  Became...  
      <Table
        sx={{
          minWidth: 700,
          height: 0,
          '& tr': {
            cursor: 'pointer',
            height: '100%'
          },
          '& td': {
            p: '0px',
            height: '100%'
          },
          '& a': {
            all: 'inherit',
            borderBottom: 'none',
            display: 'flex',
            alignItems: 'center',
            p: '16px',
            height: '100%'
          }
        }}
      >
        <TableHead>
          <TableRow>
            <ColumnHeader
            ....
