Abstract
A table processing method, device, an interactive white board and a storage medium is disclosed. The method therein includes, when an erasing instruction is received, determining whether a current erasing operation is in a first cell of a created table; and, in response to the erasing operation is in the first cell, when the erasing operation ends, updating the first cell to shrink the first cell.
Claims16
A method for table processing applied to a device supporting touch inputs, comprising:
- creating a table in a whiteboard application, and inserting a table content in the table, wherein the table content comprises a picture, a geometric figure and/or a text;
- receiving an erasing instruction for a displaying content of the whiteboard application, wherein the erasing instruction is triggered by an erasing operation of a user on an interface of the whiteboard application;
- acquiring an erasing coordinate set of an erasing trajectory of the erasing operation when the erasing instruction is received, and determining a cell where an erasing start point of the erasing trajectory is located as a first cell targeted by the erasing operation in response to the erasing coordinate set comprises erasing pixel points located in different cells of the created table;
- updating and displaying the display content of the first cell according to the erasing coordinate set, so as to make an erased content disappear with the erasing operation;
- and
- updating the first cell when the erasing operation ends, so as to shrink the first cell.
An interactive white board supporting touch inputs, comprising:
- a processor;
- and
- a storage device, configured to store a computer program executed by the processor,
- wherein, when executing the computer program, the processor implements a method comprising:
- creating a table in a whiteboard application, and inserting a table content in the table, wherein the table content comprises a picture, a geometric figure and/or a text;
- receiving an erasing instruction for a displaying content of the whiteboard application, wherein the erasing instruction is triggered by an erasing operation of a user on an interface of the whiteboard application;
- acquiring an erasing coordinate set of an erasing trajectory of the erasing operation when the erasing instruction is received, and determining a cell where an erasing start point of the erasing trajectory is located as a first cell targeted by the erasing operation in response to the erasing coordinate set comprises erasing pixel points located in different cells of the created table;
- updating and displaying the display content of the first cell according to the erasing coordinate set, so as to make an erased content disappear with the erasing operation;
- and
- updating the first cell when the erasing operation ends, so as to shrink the first cell.
A computer-readable non-transient storage medium, on which a computer program is stored, characterized in that, when the computer program is executed by a processor, the processor implements a method comprising:
- creating a table in a whiteboard application, and inserting a table content in the table, wherein the table content comprises a picture, a geometric figure and/or a text;
- receiving an erasing instruction for a displaying content of the whiteboard application, wherein the erasing instruction is triggered by an erasing operation of a user on an interface of the whiteboard application;
- acquiring an erasing coordinate set of an erasing trajectory of the erasing operation when the erasing instruction is received, and determining a cell where an erasing start point of the erasing trajectory is located as a first cell targeted by the erasing operation in response to the erasing coordinate set comprises erasing pixel points located in different cells of the created table;
- updating and displaying the display content of the first cell according to the erasing coordinate set, so as to make an erased content disappear with the erasing operation;
- and
- updating the first cell when the erasing operation ends, so as to shrink the first cell.
